QUESTIONS ABOUT YOUR SPEEDHUB 500/14
New OEM2 option via luggage rack mount with use of M5 adapter
Many bicycle frames already incorporate a 5mm drilled and tapped hole in the rear dropouts. This hole is primarily designed to accommodate the mounting bolt for luggage racks and fender mounts. If this hole happens to be located as illustrated in the diagram below, then an M5 bolt (tensile strength = 8.8) can be threaded into this hole (and through luggage rack mount etc) from the outside dropout face and then secured on the inside dropout face with our new M5 adapter. It is this M5 adapter that the standard OEM2 axleplate then grips around to anchor SPEEDHUB torque securely to the frame.
The position of this 5mm hole is important however. The hole needs to be located behind an imaginary vertical line through the hub axle. If thehols is located in front of this line, there is a risk that the axleplate will actually lever the wheel out of teh dropout and as such obviously cannot be used for SPEEDHUB torque support.
4-arm chainrings for Shimano cranks
4 arm chainrings for the 2001 Shimano XT/LX cranks as well as chainrings for nearly every conceivable crank and mounting hole diameter can be produced by various specialist firms such as Speciallites TA (France).
Suitable chainrings are available in both black or silver finishes with a choice of 36-38-40-42-44-46 and 48 teeth from

Bike Components - which are recommended? (Chains, Chain Rings, Cranks, Sprockets, Chain Tensioner, Chain Guide)
Bike Components - which are recommended? (Chains, Chain Rings, Cranks, Sprockets, Chain Tensioner, Chain Guide)
All 1/2" x 3/32" eight and nine speed chains are suitable for use with the Rohloff SPEEDHUB 500/14 although we recommend the eight speed version due to its slightly thicker link plates. All 1/2" x 1/8" bicycle chains are also compatible with the Rohloff SPEEDHUB 500/14 sprockets. These thicker chains however are by no means stronger and not recommended for use with the Rohloff SPEEDHUB 500/14. In addition to this, they are not designed for the high mileages achieved with a SPEEDHUB and thus are subject to faster wear. These 1/2" x 1/8" chains are also unfortunately too wide to pass through the Rohloff chain tensioner.
All chain rings for a 1/2"x 3/32" chains can be used together with the Rohloff SPEEDHUB 500/14.
The use of threaded sprockets in the sizes 15, 16 and 17 tooth, will produce a chain line of approximately 54mm from the frame center. This requires the use of the outer chainring from triple crank sets such as Shimano (Largest chainring: 54mm, middle chain ring 47.5mm). The middle and smallest chainrings are not required and can be disposed of. After the disassembly of the middle and smallest chainrings, the bolts for securing the largest chain ring will now be too long. For this reason the Rohloff SPEEDHUB 500/14 small parts bag includes five chainring spacers to distance the original bolts. Double chainring crank sets, should definitely mount the required chainring in the outer most position.
Sprocket sizes 15, 16 and 17 (article numbers 8220, 8221 and 8222) are all designed as reversible sprockets.
The retrofit versions of the Rohloff SPEEDHUB 500/14 are pre-fitted with a 16 tooth sprocket. 15 and 17 tooth reversible sprockets are available to purchase separately. Hereby, an individual sprocket/chain ring combination can be applied (see 'Technical data' - 'chain rings'). The 15, 16 and 17 tooth sprockets are all reversible, and therefore, can be flipped over once worn, so that the unused tooth edge can be used. A special Rohloff sprocket removal tool (Art.#8508) is required for removing and re-mounting these components.
13 tooth Threaded Sprocket (Art.#8219)
When unmounting a Rohloff SPEEDHUB 500/14 in a small wheeled bicycle (e.g. 20", folding bicycles and recumbents) the special 13 tooth sprocket will probably be required. This utilizes a different chain line (59mm instead of 54mm) and is not reversible. When using a Rohloff chain tensioner on frames with dropouts thinner than 7mm, the longer chain tensioner mounting bolt (Art.#8255) should be used - this must be ordered separately. A special Rohloff sprocket removal tool (Art.#8508) is required for removing and re-mounting these components.
Splined Carrier & Splined Sprockets (13-19 + 21 tooth):
The Splined Carrier and Splined Sprockets replace the original threaded sprockets. This upgrade shifts the chainline a further 3mm outboard so may require the use of a longer chain tensioner mounting bolt and distancing washers (if applicable) depending upon dropout/derailleur hanger thickness. Upgrading to Splined Sprocket use is possible retrospectively to all SPEEDHUBs once the Splined Carrier (Art.Nr. 8540) is mounted.
A few select special applications may be unable to utilize this wider chainline (e.g. special chain-case, chain through frame tubing, collision with rear triangle tubing etc.) so for these rare cases, we have a special, slim splined carrier (Splined Carrier S (Art.#8540S)). This carrier is exclusively for use with splined sprockets of 15 teeth or over. It is not compatible with 13 or 14 tooth splined sprockets!
Gates carbon Drive sprockets can only be used in conjunction with the Splined Carier Slim if mounted with the sprocket logo/text facing inwards towards the hub.
Rohloff Chain Tensioner (Art.#8250)
Mounting a chain tensioner is necessary on frame types A, C, D, E and G (see SPEEDHUB finder - 'frame types'), when an eccentric Bottom Bracket is not integrated into the frame design. This is necessary because there is no other possibility to re-tension the chain as the chain wears. The chain tensioner equally as necessary on frames with rear suspension, this reason for this being that the distance between the chain ring and sprocket varies as the suspension element moves the rear triangle of the frame. The span capacity of the Rohloff chain tensioner is 10 links or 20 teeth. Because a slack chain can allow sideways chain movement, we recommend that the Rohloff chain guide also be fitted up front if the bicycle is used in off-road, uneven conditions.
Rohloff DH Chain Tensioner (Art.#8245)
The Rohloff DH chain tensioner is specially designed for extreme downhill use. As opposed to the regular Rohloff chain tensioner it has a shorter link arm that is hindered from moving on the mounting point. This keeps the chain securely in position against the sprocket, guaranteeing a positive run from the chain onto the sprocket even under extreme riding conditions. The Rohloff DH chain tensioner should be used in conjunction with a chain guide up front.
Rohloff chain guide CC (Art.#8290)
The Rohloff chain guide CC prevents the chain from jumping off the chain ring on all bicycles fitted with a chain tensioner. The Rohloff chain guide is adjustable to fit with a range of different chain lines (distance between chain ring and frame center) between 52mm and 62mm. A chain tensioner alone is not sufficient to prevent the chain jumping off chain rings under extreme riding conditions.
Rohloff DH chain guide (Art.#8291)
The Rohloff DH chain guide is specially designed for extreme downhill use. It completely eliminates the ability for the chain to fall off the rear sprocket and onto the hub casing.
Can I use any type of shifter with the SPEEDHUB 500/14?
Unfortunately not. Only Twist Shifters can be used.
The Rohloff twist shifter is able to pull the two shifter cables in either direction. As the shift indexing mechanism resides inside the hub, the shifter requires no separate indexing mechanism itself.
There are no other alternative style shifters available with these features.
Other Twist Shifters available:
Tune Rolff I and Rolff II shifter
Gates Carbon Drive with Rohloff SPEEDHUB 500/14
The Gates Carbon Drive system replaces the usual bicycle chain with a carbon fiber toothed belt. These carbon fibers help increase the tensile strength of this belt and prevent stretching.
This in turn provides a high working efficiency which together with the belts other qualities, proves that the system is generally suitable for the bicycle transmission.
The main benefit of the belt drive is simply that this transmission does not require any sort of lubrication. Therefore the average life expectancy of the belt drive lies approximately at the same level (if not slighty higher) than that of a high quality chain transmission.
In order to mount the Gates Carbon Drive safely onto a bicycle however, there are several important rules which must be followed exactly just as with any other carbon fiber bicycle components.
Due to the fact that the carbon fibres of the belt can be damaged through imcorrect bending, twisting or through the belt ratcheting over the belt pulley, it is important when fitting, tensioning and when removing/refitting the wheel to pay special attention to the detailed instructions supplied with the Gates Carbon Drive System.
If the carbon fibers within the belt are damaged (which cannot always be externally observed) then the belt will inevitably break. This can lead to accident/injury or possibly death.
Because the belt drive can only be fitted to specially constructed frames, the belt drive is currently not a retrofit component for retailers or cyclists, it may only be fitted by OEM manufacturers.
Further information for manufacturers:
Rohloff are offering an adapter, which is fitted directly to the driver of the SPEEDHUB 500/14. The belt pulley will then simply be screwed onto this adapter.
All manufacturers who wish to offer the Gates Carbon Drive in conjunction with the Rohloff SPEEDHUB 500/14 can source the front belt pulleys and belts from:
Universal Transmissions GmbH, Külftalstr. 18, 31093 Lübbrechtsen,
Tel: 049 5185-60266-50, Fax: +049 5185-957192.
The rear belt pulleys can be acquired from Rohloff directly.
Rohloff will mount the adapter and the rear belt pulley on hubs ordered from us. This simply makes sense as the pulley requires special tools to secure this onto the SPEEDHUB. Because this must be orderly fitted, Rohloff will take responsibility for this task.
The Rohloff warranty is therefore only extended up to this adapter and for the correct mounting of the rear belt pulley. The mounting of the belt pulley is only undertaken in contract for the manufacturers but does not however, include any product quality control.
The company Rohloff AG does not accept any liability or warranty for the Gates Carbon
Drive or for the individual components unless they were exclusively fitted by Rohloff at the
All Rohloff hubs mounted with belt pulleys by us will be registered under their serial
number. All SPEEDHUB 500/14s which were not originally fitted with the adapter by the
Rohloff AG will automatically be excluded from warranty. Furthermore, any Gates Carbon Drive used in conjunction with a Rohloff SPEEDHUB must also be fitted with a Snubber, which is correctly fitted so that the belt is hindered from skipping over the rear belt pulley.
The company Rohloff AG insists that a frame sticker is also present informing thecustomer of the important issues that need to be addressed when utilising a Gates Carbon Drive transmission.There will be seminars offered in the future in conjunction with the company UniversalTransmission GmbH for all interested bicycle retailers as well as all OEM manufacturers who wish to offer the option of a Carbon Drive transmission. The company Rohloff will only offer original spare parts only to retailers who have taken part in such a seminar.Report with a GATES CARBON DRIVE
Hebie Chainglider for SPEEDHUB 500/14 (Typ 350 SPEEDHUB)
With the use/mounting of a Hebie Chainglider SPEEDHUB (typ 350) one has to pay attention that parts made of plastic are unable to scratch on the surface of the hub case!
With the first series of Chaingliders scratching marks occasionally appeared on the hub case by the grinding touch of the Chainglider's rear side. In October 2006 the rear part has been modified to prevent a possible abrasion. Scratches on the surface cannot diminish the stability of the SPEEDHUB case - they' re just ugly.
Now, old rear parts of the Chainglider must be exchanged to new versions.
Exchange at your bicycle dealer only!
Permitted is the use of the Chainglider with 15, 16 or 17 tooth sprockets in combination with a 42 tooth chain wheel (Typ 350-42) or a 44 tooth chain wheel (Typ 350-44). The use of a 13 tooth sprocket with the Hebie Chainglider is not permitted due to technical reasons!
While adjusting the chain tension, please pay attention to an abrasive-free sit of the chain at the hub case and check it regularly.
While riding the bike dirt particles might easily stick in the soft plastic, which can turn into a hard, abrasive surface after a while. Due to this, deep grinding grooves can emerge. In the extreme, the hub case might has to be exchanged.
A grinding-through of the hub case is not very likely, but technically possible.
Is it possible to mount the Rohloff SPEEDHUB 500/14 in a combination with a thru-axle?
The Rohloff SPEEDHUB 500/14 is constructed around a 135mm O.L.D. and designed exclusively to work in 135mm spaced bicycle frames. The new SPEEDHUB XL, introduced in 2014, is designed exclusively to work in 170mm spaced bicycle frames although as of 2016, this can be externally adapted to work in 190mm spaced frames.
135mm SPEEDHUBs and 170mm SPEEDHUB XL units are available with a choice of hollow, 10mm axle (for standard quick release skewers) or a threaded (M10x1) solid axle. These hubs are not compatible with any thru-axle standards available at time of press.
The reason thru axle versions were previously not available is simple ... the SPEEHDUB is constructed around its axle which houses the entire shifting and indexing mechanism. Increasing axle size would increase other component size and thus weight resulting in an incredibly inefficient and unmarketable product.
2016 will see the introduction of the new SPEEDHUB A12 variants. These hubs offer the ability adapt the regular SPEEDHUB construction so it can be mounted into a bicycle frame designed for 12mm thru-axles. The A12 variants will be available with a choice of 142mm, 148 boost, 177mm or 197mm O.L.D.
The 12mm axle supplied with each frame can be discarded and replaced with a special set of Rohloff adapter sleeves. Through these sleeves, M7 bolts will be inserted and threaded into the internally tapped A12 SPEEDHUB axle to secure the hub in position.
These adapter sleeves (available for DT, Maxle, Syntace and Shimano e-thru axle systems) are available in different configurations to ensure we have a compatible hub for the majority of frames out there.
As always it is imperative that the mounting information is correctly adhered to in order to ensure the safe, problem-free integration of the transmission.
Chain guard in conjunction with the Rohloff SPEEDHUB 500/14
In theory, all chain guards could be used with the Rohloff SPEEDHUB 500/14. They must however be checked, that they fit to the frame in question.
Which chain guard is correct for the frame however, is impossible for us to say - there are simply too many different combinations of type, mounting method, and frame on the market.
The firm NÖLL offers a chain guard especially designed for the Rohloff SPEEDHUB 500/14. Further information on this can be found on the web under: www.noell-fahrradbau.de
The firm UTOPIA also offers a special chain guard exclusively designed for the Rohloff SPEEDHUB 500/14.

Monkey Bone - IS-Postmount brake adapter
The Monkey Bone offers a simple method of anchoring the axle of the Rohloff SPEEDHUB 500/14 to a frame through the disc brake mount. In order to use the Monkey Bone, your SPEEDHUB 500/14 will need an OEM2 axle plate, your frame must have an International Standard disc brake interface, and your disc brake caliper must have a Postmount interface. The Monkey Bone is not compatible with IS direct-mount disc brake calipers or frames with Postmount disc brake interface.
Assembly instruction Monkey Bone for 160/180mm discbrake (English):
• 5mm Allen wrench
• Torque wrench
• T20 Torx wrench
• Frame with IS51 disc mount interface (seatstay)
• Disc brake caliper with Postmount interface
• Rohloff SPEEDHUB 500/15 with OEM2 axle plate
• Monkey Bone
• 2x M6x16 bolts (sold separately; typically included with disc brake caliper)
• 2x M6x18-20 bolts (sold separately; often included with disc brake caliper)
1. Ensure that you have the Monkey Bone that is appropriate for your disc rotor diameter (160mm or 180mm; 203mm rotors can be used with 180mm Monkey Bone and spacers (sold separately))2. Attach the Monkey Bone to the frame using two M6x18-20 bolts. Ensure that slot for OEM2 axle plate faces the dropout. Tighten bolts to a torque of 6 N-m/51 in-lbs.3. Connect disc brake caliper to Monkey Bone using two M6x16 bolts. Leave bolts loose enough that caliper can slide side to side.4. Install wheel into dropout taking care to align slot in end of OEM2 axle plate with cutout in Monkey Bone and disc rotor between brake pads.5. Check position of EX shift arm with OEM2 axle plate engaged with slot in Monkey Bone; reposition axle plate as needed for desired cable routing using T20 Torx wrench (see Rohloff owners manual). Tighten axle plate screws to a torque of 3N-m/25 in-lbs.6. Fully seat axle in dropout before tightening quick-release lever or axle nuts. Threaded axle nut torque: 35 N-m/310 in-lbs; Pitlock or bolt-on skewer torque: 7 N-m/60 in-lbs.7. Follow brake manufacturer’s recommendation for setting brake caliper position. Tighten brake caliper bolts to a torque of 6 N-m/51 in-lbs.CAUTION: Use of the Monkey Bone with some frame geometry can result in the wheel being pulled out of the dropout while pedalling due to the forces exerted by the Rohloff SPEEDHUB 500/14 onto the frame. When the anchoring point of the OEM2 axle plate is located in front of a line parallel to the dropout slot, there is a component of the reaction force in the lowest gears that tends to push the axle down and out of the slot. Per Rohloff’s recommendation, the Monkey Bone and OEM2 axle plate combination are not recommended for use on frames with such geometry (see page 30 of the Rohloff owner’s manual for more info). Use of the Monkey Bone and OEM2 axle plate is entirely at the user’s own risk. The forces applied to the disc brake mount by the Rohloff SPEEDHUB 500/14 can damage some frames. Please contact your frame manufacturer to determine whether this setup is appropriate for your frame and whether it affects your frame warranty.
PITLOCK available for the Rohloff SPEEDHUB 500/14
The pitlock set M10 Rohloff mono is recommended for frames which incorporate dropouts that are thicker than 8mm and use a TS axle. For this you will require the appropriate Rohloff axle plate with a longer axle stud.
8228L TS OEM2 long
8233L TS Standard axle plate long
8235L TS OEM long
Frames that utilize dropouts thinner than 7mm can use the PITLOCK Securing Set M10 Rohloff dual for mounting. Make sure that the threads protrude the dropout slot far enough to mount the securing components.
Safety-catch for (slideable) rear bolted dropouts:
This new safety-catch is for bolt-on adjustable dropouts and is designed to prevent an easy removal of your rear wheel. Dispite having a PITLOCK securing the rear wheel, it is still possible that a thief may be able to steal the complete rear wheel simply by unbolting the not-protected rear dropouts. To prevent or to hinder this, it is now possible to mount this PIT- dropout security system.
All important information can be found on the homwpage of Pitlock!
Schlumpf Speed Drive, High Speed Drive, Mountain Drive
The Schlumpf Speed-drive works like two chainrings with a large difference in size.
With the additional transmisson ratio of 1:1.65 the gear ratio of the Rohloff SPEEDHUB 500/14, when used in conjunction with the Schlumpf Speed-drive, will be increased to 868%.
When fitting a Schlumpf transmission, please bear in mind that it is still important not to undercut the smallest permitted sprocket ratios (see 'sprocket ratios').
The Schlumpf Mountain Drive is not permitted for use in conjunction with the Rohloff SPEEDHUB 500/14.
The Schlumpf High Speed Drive (1:2.5) is not permitted for use with the Rohloff SPEEDHUB 500/14 due to its standard 27 tooth integreated chainring. A number of alternative chainring sizes are however available from schlumpf so as to not undercut our smallest permitted sprocket ratios.
For versions with compatible chainrings please contact schlumpf directly.
AXLE PLATE AND DROPOUTS
Axle type change between TS, CC & A12.
Changing the axle from CC, TS or A12 to a different type is retrospectively not possible. The complex SPEEDHUB gearbox is build around and calibrated for each respective axle so swapping this out would require other components to be recalibrated and various other gears to be swapped in order to remain compatible. This is not a cost effective solution and as such will not be offered.
Horst link. Can the Rohloff SPEEDHUB 500/14 be built into a frame with a Horst link?
With this suspension principle, a joint is to be found directly in front of the dropout.
The chainstays and the dropouts do not form a sturdy structure.
In this case the long torque arm would disable potential for the rear swing arm to move.
This is obviously not the point of a full suspention frame.
The Rohloff SPEEDHUB 500/14 can therefore only be used on a rear 4-link frame (with this Horst link) when mounted in conjunction with an OEM or an OEM2 axle plate.
Can the Rohloff SPEEDHUB 500/14 be used on a racing bike?
The Rohloff SPEEDHUB 500/14 was constructed as an alternative to derailleur gears for mountain, trekking and city bike use.
The information over derailleur gears from these areas (working efficiency, robusticity, weight and gear ratios) was taken to construct the Rohloff SPEEDHUB 500/14. The benefits were taken into concideration along with the known disadvantages (wear, maintenance and care work, constant adjustments etc.) that needed to be eliminated.
These problems are generally the same for all bicycle types. However, the factor of weight plays a much larger role in the racing bike field, the need for such a large overall range of gears is also not needed. Most riders choose to run a finer ratio (smaller gear increments), the problem of dirt is also not so problematic for the racing biker.
It is for these reasons that the Rohloff SPEEDHUB 500/14 was focused specifically for MTBs. You can of course mount the Rohloff SPEEDHUB 500/14 into a modern racing frame without any problems (as long as the frame spacing is 135mm). There are no current plans on building a special lightweight SPEEDHUB version for racing frames which for a frame spacing of 130mm.
Chain - Which chain with a Rohloff SPEEDHUB 500/14
All 1/2"x3/32" eight speed chains are suitable for use with the Rohloff SPEEDHUB 500/14.
With the Rohloff SLT-99 chains, both the eight and nine speed versions can be used. This is because the Rohloff SLT-99 chains are less elastic, and therefore, causing less wear on the chainring and sprocket due to their identical link plates.
All 1/2"x1/8" bicycle chains are compatible with the Rohloff SPEEDHUB 500/14 sprockets.
However, these thicker chains are by no means stronger and not recommended for use with the Rohloff SPEEDHUB 500/14 due to their relatively short lifespan
In addition, these chains are too wide to pass through the Rohloff chain tensioner if in use.
Smallest permittable sprocket ratios
The sprocket ratio on the Rohloff SPEEDHUB 500/14 (e.g. 42/16) converts the slow rotational speed at the crank into a fast rotational speed at the sprocket and thus reduces the input torque for the Rohloff SPEEDHUB 500/14 simultaneously.
To prevent overstraining the hub, a minimum sprocket ratio of 1.9 must be used. With the available sprockets these minumum possible sprocket ratios are:
~32/17, ~30/16, ~28/15 and ~26/13.
This resembles a derailleur transmission of 20/40. Larger chainrings can be used without exceptions.
If mounting the SPEEDHUB 500/14 on a tandem or if the rider weighs over 100kg, the following sprocket ratios are the lowest permitted for use:
34/13, 38/15, 40/16, 42/17.
Maximum chain height when utilising a 15 tooth threaded sprocket
When utilising a 15 tooth threaded sprocket in combination with the SPEEDHUB, it is important to make sure that the maximum chain height does not exceed 8.5mm. There is otherwise the risk that the chain may come into contact with the hub shell itself. This could lead to wear marks upon the shell plus will increase the friction of the system and create excess transmission noise while in use.
There are no such limitations for the current Rohloff splined sprockets.
The current derailleur chains generally fit within the tolerances that I have mentioned above. BMX, singlespeed and IGH chains usually use a much higher link plate than 8.5mm and lead to the problems previously mentioned.
Crank rotation whilst pushing
Should the bike be pushed, it is possible that the cranks could also start to rotate.
This occurs due to the hub seal automatically activating the sprocket.
A very light running bottom bracket with poor quality seals will make it much easier for the cranks to rotate.
A drop of Rohloff cleaning oil (Part No. 8402) through the holes in the sprocket onto the hub seal will reduce this acivating effect.
Wherever power is transmitted, friction is produced within the mechanical system. In general this friction is lost as heat and is referred to as power loss.
While observing gear systems, two different types of power losses can occur. These are power dependent and power independent losses. Power independent loss is e.g. friction within the seals. Whether the bike is being pushed, ridden downhill or ridden with extreme force upon the pedals uphill, the friction force within the seals remains the same. Here the friction losses vary according to the condition of the seals (smooth or rough surfaces) and, depending on the speed, are very small producing between 1W and 3W of power loss. This small power loss is enough to bring a free spinning wheel to a stop just after a few rotations, or it makes the cranks rotate while the bike is being pushed.
The power dependent losses work completely differently. Whilst pedalling, the friction loss is produced between the tooth flanks of the gears and all bearings in use. Each different gear system produces a different percentage of power loss depending upon the mechanical construction. If the working efficiency of a gear system remains at e.g. 95%, the remaining 5% of the transmitted power is lost through friction. So, if a rider is pedalling with100W of input power, the rear wheel will only transmit 95W of output power onto the road because of the 5W power loss. If the input power is increased to 300W, the power loss will rise accordingly to 15W.
Should the rider increase his tempo to a fast, high blood pressure sprint with 1000W of input power, 50W of will be lost through friction reducing the output power considerably. This example shows clearly how important a good working efficiency is. The input power given by the rider defines the amount of power loss. In the examples this could be 5W, 15W or 50W. Through special constructive developments like an increased number of teeth per gear and the choice of using roller bearings for the planetary gears, running the gearbox within an oil bath the extremely rigid construction of the overall gearbox etc, the working efficiency of the Rohloff SPEEDHUB 500/14 is brought up to 96% (for gears 1 to 7) and 98% (for gears 8 to 14).
This working efficiency is comparable to a derailleur gear system. Common seven speed gear hubs reach a working efficiency of approx. 90% (gear #1) and 98% (direct drive gear). Again we observe our test rider, now pedalling up a hill with 200W of input power. While using the Rohloff SPEEDHUB 500/14 or a derailleur gear system, he will lose approx. 4% of output power, or riding in gear #4 as this is comparable to the first gear of a seven-speed gear hub, which is 8W. With the same input power but using a seven-speed gear hub, our test rider will lose approx. 20W of output power. Adding approx. 2W of power loss caused by the seals for the Rohloff SPEEDHUB 500/14 would bring the overall loss of power with the Rohloff SPEEDHUB 500/14 up to 10W against 20W with the common seven-speed gear hub. Conclusion: Power independent losses like the friction of the seals will have the same effect as a lightly rubbing brake block. This brings a free spinning wheel to stop but is barely noticeable whilst riding. But it is easy to recognise on a bicycle repair stand.
On the contrary, power dependant losses mean that a particular percentage of the transferred power is lost and not so easy to be detected on a bicycle repair stand, because the measurement can only really be made with the bicycle being ridden with the appropriate measuring aids.
The Rohloff SPEEDHUB 500/14 has an extra fact to take into consideration.
While the pedals are rotated backwards, the sprocket is being forced to rotate backwards. Therefore, the planetary gear system also has to run in reverse. The sun gears, that are fixed to the axle for the particular gear that is currently selected (when the wheel is being driven forwards) now rotate with a ratchet function over the pawls. Additional to this, it is possible that this freewheeling situation can be carried out by the component numbers 14 upper and 19, or 19 and 26 on our explosion diagram. The method that is used to allow this is 100% dependant on which gear is currently selected.
It is therefore easy to see that if the pedals are rotated backwards it causes more friction in turn.
If the rear wheel is freewheeling forwards and the cranks refrain from rotating, the first two planetary gear systems (twin planetary gear carrier) remain motionless and the planetary gear system 3 rotates. The freewheel mechanism to enable this is to be found situated in the middle of the planet carrier 2. The flat-toothed components (numbers 14 lower, 37, 38 on our explosion diagram) allow this gear carrier to freewheel. Which of these parts are active all depends upon which gear is currently engaged (gear # 1-7 or gear # 8-14).
As opposed to a derailleur gear system, the backward rotation of the planetary gear mechanism is not comparable to that of a running freewheel on a derailleur gear system.
Why do i need a chain tensioner?
The derailleur gear system requires a different length chain depending on the gear selected. This is due to the different sizes of the sprockets in use. When smaller sprockets are in use, there is an section of chain too much that needs to be tensioned, the rear derailleur does this by also including the chain tensioner function.
With the Rohloff SPEEDHUB 500/14, only one sprocket combination is ever in use (e.g. 46/16 ).
It is only possible to shorten a bicycle chain in steps of one link at a time (1 link = 1 male and 1 female link). You will find that with most frames, the chain will still be a few mm too long. It is these few mm that leave the chain slack and can allow it the to spring off of the sprockets in some circumstances which of course would lead to a spontaneous loss of drive causing accidents and injury to the cyclist.
Therefore, on hardtail frames without an eccentric Bottom bracket which use vertical dropout slots a chain tensioner will always be needed. On such bicycles it is not possible to pull the wheel backwards in order to tension the chain.
Is it possible to use the Rohloff Chain tensioner also for other gearhubs or singleespeed ?
In principle yes, however the measurement from the dropout outside face to the sprocket center must be no less than 24mm!
WHEEL/ SPOKES/ NIPPLES
Rims for the Rohloff SPEEDHUB 500/14
The Rohloff SPEEDHUB 500/14 is only available in a 32 or 36 spoke version. The ideal rims to be used are triple hollow aluminum rims from known manufacturers with reinforced spoke eyelets (min. 4,4mm).
MTB and ATB rims from:
Rigida Andra 10/20/30/40/210/Edge21/Edge28
You can use them with the Rohloff Speedhub 500/14 without any problems.
Why do spokes break?
Spokes always break as the result of an irregularity in the wheel lacing.
Play between the hub and the spoke. Each spoke is subjected to one load cycle (loading/unloading) during each complete rotation of the wheel.
Each spoke in a bicycle wheel that has been ridden over 2000 km, for example, has experienced one million load changes.
If there is even the slightest play between the spoke and the hub flange, a broken spoke is just a question of time. The spoke continually jerks back and forth in the flange, which subjects the spoke bend/head to massive stress. This causes the material to become brittle, the spoke can then no longer bare the load and breaks at the head.
Place washers underneath the head of any spoke where play is felt at the hub flange.
Insufficient spoke tension. Loose spokes cause a wheel to become unbalanced. The weaker the tension, the more the spoke bends when the bike is ridden. This causes the spoke to move within the spoke hole of the hub flange, and the same negative effects arise as when there is play between the hub and the spoke.
Optimally high tension improves the balance of the wheel by reducing wheel lace movement to a minimum. The higher the spoke tension, the more effective wheel overload can be distributed among multiple spokes.
OIL AND LUBRICATION
All-season oil and cleaning oil?
All forms of multi geared bicycle transmissions use a variety of movable parts regardless of whether they are derailleur or IGH style transmissions. These components need to be lubricated regularly to uphold the manufacturers warranty, to ensure easy operation and correct functionality as well as to protect these components against corrosion and premature wear.
The process of oiling chain drives is due to the principle of lubrication loss over time.
So far the following recommendation remains valid:
Derailleur gear systems:
The chain should be lubricated with a viscous chain lubricant at least every 500km. Lubrication is absolutely necessary following bicycle use through rainy conditions so that the oil can force any penetrated moisture out of the joints and thus prevent corrosion. Likewise the joints of the front and rear derailleurs should be lubricated with a drop of oil. Comprehensive hub maintenance should be completed every 3000km. The front and rear wheel hub and freewheel bearings should be checked and re-greased or replaced when necessary. The same applies to the jockey wheel bearings. The extent of component removal and preparation for these service tasks varies according to each application.
Standard IGH transmissions:
The chains of gear-hub drives are not subjected to such high stress situations as derailleur chains are. They are not required to cope with sideways movement, nor are they required to climb and fall from one sprocket to the next. With regards to this, these chains are not in need of such high maintenance. IGH chains only require lubrication approximately every 1000km - although on principle, these should still be re-lubricated following every rainy tour. Standard IGH transmissions are said to be low maintenance. The bearings of these IGHs are filled with grease, the teeth of the gearwheels are greased and the surfaces of the planet-bearings and ratchets are lubricated with a few drops of oil. With intensive use the oil of the planet-bearings is consumed and the grease is pushed out from the bearings. The same happens to the tooth flanks of the gearwheels. Grease is forced away from the tooth flanks and cannot fulfil its function of lubricating the gear mechanism. To prevent the transmission from running dry, the hub should be stripped and re-greased at least every 4000km in order to ensure a long life. As above, the extent of component removal and preparation for these service tasks varies according to each application.
Rohloff SPEEDHUB 500/14:
Similar to an automotive transmission, the Rohloff SPEEDHUB 500/14 uses a sealed oil-bath lubrication. In the SPEEDHUB case, a shot-glass of special lubricant (25ml) is more than sufficient to lubricant the transmission for 1 year or 5000km of use. The movement of the gear system ensures that the oil is evenly dispersed around the hub coating all components with enough oil to guarantee smooth operation and durability. Because the Rohloff SPEEDHUB 500/14 can be ridden for so much longer than other bicycle transmissions without additional lubrication except for a few drops on its chain (see IGH above), it is referred to as being maintenance-free.
The Rohloff SPEEDHUB 500/14 is filled with an all-season oil. This oil copes with a large temperature range ensuring that expedition cyclists will not experience any oil viscosity related issues. In addition to lubricating the bearings and gear system of the SPEEDHUB, the oil also helps to dampen the noises created by the high efficiency straight-cut gears that are used. the noises created by the high efficiency straight-cut gears that are used.
Wheel rotates with great resistance
Pushing the bicycle
The cranks can rotate when the bicycle is pushed along. This is due to the rear hub seal driving the sprocket onwards due to the contact between the two components. Poorly sealed and thus light running bottom brackets increase the ease with which the cranks can rotate. Add a drop of our SPEEDHUB cleaning oil (Art.#8402) through the holes of the rear sprocket and direrctly onto the hub seal to reduce this effect.
Excessive resitance on bikes without a chain-tensioner
Excessive rotating resistance on bikes with adjustable dropouts or eccentric bottom brackets can only be checked with the use of a mounting stand.
Shift into the highest gear (#14) and bring the wheel up to speed using the cranks. Now hold thecranks stationary and count the wheel rotations.
The wheel should rotate a minimum of 15 times.
Chain-tensioner jockey wheels are dry and don't rotate freely
Grease the axles of the chain tensioner and replace the jockey wheels if necessary. See Owners Manual "Service" 2. or "Repairs" 2.
Gear display is not aligned correctly
Alter the cable adjusters, see Owners Manual "Service" 2.
Freespinning (after a gear change)
Gearbox oil too thick
- Carry out an oil change with an intensive rinsing,
Riding the bike in temperatures below -15°C
- Rinse the SPEEDHUB intensively and fill with a mixture of 50& All Season Oil and 50% Cleaning Oil
The SPEEDHUB 500/14 axle is secured too tightly into the frame which could damage internal components.
- CC (quick-release) axles using a security skewer (Pitlock / Pinhead / Allen Key) = max. 7Nm.
- TS axle nuts = max. 35Nm
Oil drain screw is re-inserted too deep following an oil change. Now places pressure upon internal transmission components.
- Oil drain screw head must not rest deeper than flush with the outside hub-shell material.
Check that both freewheel springs are present and seated correctly see Owners Manual "Repairs" 1.1 and "Service" 5.3.
If chain, sprockets or jockey wheels of the chain tensioner are worn, then
the operational safety can no longer be guaranteed. Because of this, we are unable to excluded the possibility that the chain jumps off sprockets, especially under high pedal loads (up-hill). For this reason, it is vital that all other elements of the bicycle transmission are regularly inspected and replaced where necessary to ensure the safe use of the bicycle!
If the problem cannot be resolved, then bring your bicycle to your local dealer for further diagnosis.

Low temperature/winter shifting issues
Problem-free cycling with a SPEEDHUB 500/14 through winter.
The SPEEDHUB is filled with 25ml of All Season Oil, which allows a problem-free operation down to approximately –15 °C (+/- 5°C).
If the bicycle however stands for long periods in the cold (e.g. outside over night with temperatures of down to –10°C), then the cooled gear-unit retains this temperature throughout the following day and this can lead to shifting problems.
These shifting problems are identified as freewheeling in the gear numbers 4,6,7 and 11,13,14 directly following a gear change.
To ensure therefore a safe and problem-free operation throughout the winter months, the All Season Oil should therefore be thinned with 50% of our Cleaning Oil (total oil in gear-unit remains 25ml).
The safe operation of the SPEEDHUB can now be guaranteed down to temperatures of approximately –30 °C.
The thinned oil mixture can also be ridden problem-free through the warmer summer months.
The only disadvantage being that the noises produced in summer will appear louder and the amount of sweat oil may increase.
A further problem that may occur in the cold winter months is that the shifter cables could freeze if the cables are routed under the bottom bracket. Any penetrated moisture tends to collect in this low point and it freezes here in minus temperatures. In this case, the twist shifter refuses to rotate. If this occurs, the water within the cables must be thawed and allowed to drain out from either end. Following this, the SPEEDHUB should once again operate undisturbed and correctly.
Too much play in the twist shifter (more than 5mm)
Readjust the cable tension, see Owners Manual "Service" 2.
Can the Rohloff twist shifter be mounted on racing bars?
The twist shifter for the Rohloff SPEEDHUB 500/14 can only be mounted upon straight or slightly bent bicycle handlebars with a diameter of 22.2mm (7/8").
Due to the shifters length of 60mm, it will not pass around the bends of racing bars or a Randonneur (racing bars with a lightly upward swung horizontal section).
Only special handlebars allow the twist shifter to be mounted at the top.

Conversion of internal to an external gear mech
In principle, such a conversion is possible, but it should make sense.
Bikes with a long torque arm and parts like mudguards, luggage carriers, kickstands make it almost impossible to place an external gear mech in a reasonable position.
If in doubt, please contact you bicycle dealer to resolve the issue directly with the object in question.
When using an OEM or OEM 2 axleplate, the mounting of an external gear mech is usually problem free when routing the cables via the chainstay.
Can the SPEEDHUB 500/14 be used with Magura disc brakes?
In general, the Rohloff SPEEDHUB 500/14 is compatible with all Magura brake discs.
The use however of an OEM 2 axle plate is not possible to be used in conjunction with the SPEEDBONE and a caliper adapter (Magura Adapter 16) from 160mm - 180mm.
The use of this together with a post mount brake caliper is also not possible.
In contrast, the use of the Magura Adapter 15 (160mm - 190mm, see photo) is possible.
Depending upon the width of the dropout slots the use of spacers may be required between the adapter and SPEEDBONE to prevent the adapter from coming into contact with the SPEEDBONE.
Therefore, the OEM2 version of the SPEEDHUB 500/14 and SPEEDBONE may only be used exclusively with Magura 160mm and 190mm brake discs.
Generally Magura 160mm, 180mm and Gustav M 190mm brake discs are available.
Further Information over Magura brake discs can be found under www.magura.de
Problems with the OEM2/SPEEDBONE mounting and (Magura) brakes!
The OEM2/Speedbone mounting in combination with disc brakes is designed around International Standard 2000. An interim adaptation of any kind has must be observed critically, simply because there too many influential factors that may come into play.
In combination with Magura brakes, the follwoing combinations are not possible:
- Quickmount Adapter 1 (International Standard to Post Mount) for disc diameter 160mm.
- Adapter 16 for larger discs (180mm instead of 160mm)
All disc brakes
Be careful with an adaptation of international standard 160mm disc to PostMount 180mm disc. The danger is that adapter and Speedbone may come into contact (this can be rectified with distancing washers).
There has been a change made in the running series of Speedbones. As from 2006 all Speedbones supplied will no longer incur the above mentioned issues.
Conversion of a Rohloff SPEEDHUB 500/14 to a Disc Brake version
Every non-Disc Brake version of the Rohloff SPEEDHUB 500/14 can be converted for Disc Brake use. This can only be done at the Rohloff Service Department (Germany). Therefore, the hub has to be sent to us. This transaction has to be done by your local dealer in cooperation with our distributors!

MAINTENANCE AND SERVICE
Warranty: Rohloff SPEEDHUB 500/14
The Rohloff SPEEDHUB 500/14 has been exclusively constructed for the bicycle drive.
Please, read the attached owners manual first, before mounting and using the SPEEDHUB 500/14!
We guarantee a flawless and technical fault-free running of the Rohloff SPEEDHUB 500/14 for a period of two years after date of purchase. Not included in the warranty is a normal amount of wear of all wearable parts. Wearable parts are those parts which are subject to an amount of wear due to their function.
Wearable parts are: hub seals, jockey wheels on the chain tensioner, sprockets, shifter cables (internal gear mech), grip rubber of the twist shifter, break discs.
Non-wearable parts are: encapsulated gear box bathed in oil, hub case and twist shifter housing (external gear mech).
Any warranty extinguishes with damages, which are caused by: accident, using of brutal force, changes of built of any kind, incorrect mounting, incorrect use, inadequate maintenance, taking apart the gear box into its components.
All wearable parts mentioned above generally are subject to wear. The amount of wear depends on maintenance, service, how the product is used and cared for (running performance, pressure, rain and snow rides, dirt, salt, etc.) With regular cleaning and oiling, using the appropriate means, the life span can be elongated. A replacement is definitely recommended, when the wear limit is reached.
To guarantee the safe function, these parts must be replaced as soon as they are no longer capable of performing correctly. Therefore, it is necessary to have a service check and oil-change made, at the owner's expense, once a year or after 5.000km by a professional bike workshop, who is obligated to check over all the workings of your bike regularly and to replace worn parts.
The service check is to be documented on the service card by this professional bike workshop. In case the owner does not take much care with it, any claims for replacement extinguish, which can be traced back to a neglected service check.
Within the context of warranty, it remains our choice to perform replacement or any other work on the product.
The warranty transaction takes place over the bicycle shop only. Please keep in mind the filled in service card has to be sent with the hub in case of warranty claims. With complete bikes, which are equipped with Rohloff products in series, the warranty transaction of Rohloff products is made directly between the bicycle dealer and the Rohloff AG.
The regular service check in accordance with our instructions secures the warranty entitlement and keeps the high value of your Rohloff SPEEDHUB 500/14 in future.
Rear wheel postage in cases of guarantee
Any problems with the Rohloff SPEEDHUB 500/14 should be firstly taken up with your local dealer. They are all informed over the workings and charictaristics for posible failure diagnosis.
Should it be that it is a genuine guarantee case, then we will send a delivery firm to the address to collect the wheel. The local dealer must inform us that this will need to happen. The wheel will be waited upon and dealt with as soon as possible, the whole process can normally be carried out within a week.
It is however very important that the wheel is cleaned, the brake disc is removed and that (where applicable) the external gear mechanism is well protected. The whole wheel must be properly and carefully packaged (the tyre works well to protect the rim). We will cover the costs for any small damages posibly caused by the delivery firm. The local dealer should include a detailled failure diagnosis or at least a note of failures noticed (e.g. a copy of the servive/repair contract for work carried out on the hub) inside the package.
How to clean a Rohloff SPEEDHUB 500/14
Only wash with water & gentle cleaning fluids. The use of high-pressure wash or steam cleaning inreases the risk of water comming through the seals and into the workings of the hub. For this reason, the use of these cleaning methods is not allowed.
The wearable parts are:
- jockey wheels on the chain tensioner
- shifter cables
- brake disc
- rubber grip
How quick the parts wear is down to how the product is used and cared for (pressure, dirt, weather and care). To guarantee the safe function, these parts must be replaced as soon as they are no longer capable of performing correctly. Let the workings of your bike be regularly checked over by a professional bike workshop.
Maintenance and care of the Rohloff SPEEDHUB 500/14
The gears of the Rohloff SPEEDHUB 500/14 are protected from dust and harmfull moisture due to running in a service-free oil bath. The maintenance and care of the Rohloff system is limited to the following points:
- Chain and chain tensioner (where applicable) should in regard to regular use (at the latest after riding in rain) be cleaned and relubricated.
- The cable box of the external gear mech should be demounted approx. every 500km, cleaned and the cable pulley lightly greased from the hub-facing side.
- The shifter cable tension should be regularly checked, and when neccessary altered by the cable adjusters.
- The Rohloff shifter cables are made from high-quality stainless steel and run in a nylon liner. They must not be greased or oiled. The stainless steel/nylon combination runs service-free.
All 14 gears of the Rohloff SPEEDHUB 500/14 are selectable through one twist shifter, so that in one turn it is possible to change up or down by one or more gears.
The red mark on the twist shifter casing next to the gear numbers informs the user of which gear has been selected. The assembly instructions show the twist shifter being fitted to the right hand side of the handlebars, however, in special circumstances it is possible to fit the twist shifter to the left hand side.
When rotating the twist shifter in the direction of #14, a harder, faster gear is selected. When rotating the twist shifter in the direction of #1, an easier, slower gear is selected.
In contrast to other gear systems on the market, with the Rohloff SPEEDHUB there is no delay between gear selection on the twist shifter and gear change in the hub. The moment the notch can be felt in the twist shifter, the gear has been changed. Therefore a quick and failure free gear change is possible whilst riding and also when stationary.
When changing, gear coupling elements inside the hub must move and when there is more pressure on the pedals it is obvious there is more pressure on these coupling elements resulting in a harder gear change. Whilst stationary or when there is less pressure on the pedals, the twist shifter has less resistance and therefore a lighter gear change is possible. In a situation whereby it is not possible to reduce the pressure on the pedals (e.g. hill climbing), it is still
possible to change gear quickly and smoothly. Simply change gear when the cranks are in a straight up-down position where hardly any pressure is being applied upon the pedals.
Changing gear with the Rohloff SPEEDHUB 500/14 with pressure on the pedals is not necessary when being used appropriately. However due to the robust construction of the Rohloff SPEEDHUB 500/14 changing gear under pressure is possible and is not harmful to the hub. It is however possible that when changing gears under high pressure the hub could accidentally fall into a neutral gear, this is due to the coupling elements not seating correctly into the next elements and therefore rebounding back. If this occurs the rider could lose
balance and crash. Changing gears under high pressure is at the riders own risk.
If changing up and down slowly or under high pressure between the gears #7 and #8, it is possible to fall momentarily into gear #14.
When riding in particular gears, one of two different types of riding noise could be heard. Construction characteristics prove that in most gears a free-spinning noise can be heard which is particularly noticable in gear #7. When riding with a higher pressure upon the pedals, a higher frequency can be heard through the gears #5, #6 and #7 which is typical for straight-toothed precision gears. Through different frame types these noises can be of different volumes in regard to noise transfer (the tubes of the frames react as a resonator for the sound waves).
Different noises are noticable whilst freewheeling depending on which gear you have currently selected. This is due to different parts of the gear mechanism rotating within the hub.
Weight comparison: Rohloff SPEEDHUB 500/14 - Derailleur gears
The Rohloff SPEEDHUB 500/14 is with a weight of 120g per gear, the lightest gear hub on the market. The gear range is the same as high quality 27 gear derailleur systems due to the 14 gears within the hub being evenly spaced out at 13.6% increases. With the Rohloff SPEEDHUB 500/14 there is no longer a need for the following parts:
- Front and rear derailleur
- Two shifters including shifter cables
- Rear hub with cassette
- Small and middle chainrings
- The total average weight of all these components is approx. 1600g.
The weight of a fitted Rohloff SPEEDHUB 500/14 CC OEM including twist shifter, shifter cables and cable guide is approx. 1820g.
The comparison between the Rohloff SPEEDHUB 500/14 and the derailleur system shows only a slight increase in weight. For that, the user receives a service-free, dirt-free full-encapsulated, user-friendly gear system and high reliability along with a long life span.
Technical changes in the current series
The number af axle plate screws (countersunk screws) shown in the Rohloff SPEEDHUB 500/14 workshop from 25-6-1999, is no longer correct. Instead, only Torx (M4 - TX20) screws are now being used.
Chain tensioner spring: In late autumn 2002 the spring in the chain tensioner was swapped for a new spring with a longer arm. With this in place, the chain tensioner recieves an incredible increase in performance whilst the risk of damage to the spring is also reduced to a minimum, even if the chain is not sufficiently long enough on rear suspension bikes. The new spring can be fitted to all the old style chain tensioners. The conversion kit is Part No 8248.
At the beginning of 2003, a quick change axle ring was introduced to replace the old one piece axle ring. This is easy to spot as it is now only secured in place by 5 visible axle plate screws and not 6 as before. The sixth screw is under the axle plate, holding the axle ring securely in place. The benefit of this development is that, should the hub cable need to be changed, the axle plate can stay in place making the whole job quicker and easier. The one-piece axle ring can be easily replaced by the new, quick change axlerin
A new indexing spring took over onwards from Serial number 18100.
A new generation hub and hubcap seal was fitted to all SPEEDHUBs onwards from Serial number >25300. This can be easily identified by the outer metal ring and the deep blue colour of the rubber.
Onwards of Serial number 33000, all SPEEDHUBs were fitted with a slightly over-worked shifting shaft. the 7-8 or 8-7 gear changes now run the risk of finding gear # 11 instead of gear # 14. This will however only happen if shifting very slowly or with incredible force upon the pedals.
Spoke hole revision. Updated hub shells have spoke hole diameters of 2,7mm:
polished aluminium 43559, red powder coated 43384, black anodised 44321
After Serial number 75.000 all hub shelld are laser etched with the Serial number.
They therefore now offer an optimum protection against theft as the Serial numbers can no longer be removed without leaving visible signs.
The hub sticker may now be removed from the hub shell without any loss of guarantee.

Transportation of the Rohloff SPEEDHUB 500/14
If transporting a bike fitted with a Rohloff SPEEDHUB 500/14, care should be taken that the rear wheel is transported in an upright position. In a car or an aeroplane, there could be great changes in the air temperature/pressure.
When the wheel lies on its side, oil could seep out of the seals because the oil is sitting directly over these seals on either the left or the right side. Transportation in the upright position will prevent the air temperature/pressure in having an effect over the Rohloff SPEEDHUB 500/14.
If it is not possible to transport the wheel in the upright position due to according packaging requirements, don't worry. The leakage of oil will not cause any damage.
TRAVELING WITH YOUR SPEEDHUB 500/14
Trailer in conjunction with SPEEDHUB 500/14?
In general, the use of a trailer in conjunction with the SPEEDHUB 500/14 is entirely possible!
It could occur though, that with different types of trailers, that the torque support must be cleared.
In this case, please ensure to ask the manufacturer if there are any known problems at the time of purchase.
For rear wheels with threaded axle or gear hubs are adapters available.

Info for the tour
The Rohloff SPEEDHUB 500/14 has proved from the start that it is the optimum gear system, especially for tours and long journeys due to its durability, long life and the strength of the final wheel itself.
Of course, good materials should always be used, so that the other parts on the bike start out not ruined, dirty, over lubricated, worn, so that their function is impaired or even damaged.
Therefore, we suggest that in regard to poor parts on the bike you should always carry a few important tools with you.
Our service team is on the net and you can Email us.
We endeaver to help with any technical problems and, when neccessary, ship spare parts out all over the world. However, due to extremely high postage costs or lack of service in some countries, this is not always possible.
For this reason you should take into consideration carrying spare parts (in case of accident damage or excessive wear), the handbook and also a range of tools along for the tour.
Tools for on the go:
- 2mm allen key (male/female connectors, cable pulley screws)
- 2.5mm allen key (twist shifter securing screws)
- 3mm allen key (drain screw)
- 5mm allen key (securing bolts for torque arm/chain tensioner)
- 8mm wrench (for turning the shifting rod)
- 15mm wrench (for axle nuts where applicable)
- Chain lubricant and grease
- Torx TX20 (all other bolts of the Rohloff SPEEDHUB 500/14)
For long distance journeys the following should also be taken along:
- Oil change kit (Art.Nr. 8410)
- Sprocket tool (Art.Nr. 8501)
- Spare chain and sprocket
- Spare spokes
- Spare shifter cables
- Internal gear mech: spare hub cables (Art.Nr. 8271) or the complete axle ring set (Art.Nr. 8572)
Emergency repairs on the go
Several repairs can be improvised in case of emergencies
Breaking of a hub cable (internal gear mech):
Remove the axle plate and the cable pulley, then with an 8mm wrench select a suitable gear (ex. gear #7). Riding further is now possible using this one gear.
Breaking of a shifter cable (internal gear mech):
Pull a hub cable until a suitable gear is found (eg gear #7). Riding further is now possible using this one gear.
Male or female connector lost or damaged (internal gear mech):
Join the hub cable and the shifter cable together with the use of an electric cable connector or binding wire.
Breaking of a shifter cable (external gear mech):
Remove the cable box and use an 8mm wrench select a suitable gear (eg gear #7). Riding further is now possible using this one gear. Safety ring (and pin) of the quick release on the torque arm (where applicable): Use an M6 nut and bolt or improvise by using binding wire.
Loss of oil:Loss of oil through sweat oil or the light leakage of oil through the seals is harmless. Therefore, travelling further until the next oil change (at 5000km intervals) is possible.
Weberkupplung – In Combination With Rohloff SPEEDHUB 500/14?

Is the Caliber 2 also suitable for measuring 10 speed chains?
The Caliber 2 chain wear indicator is suitable for all derailleur chains with the dimensions 1/2" x 3/32" and therfore this can also be used with 10 speed chains.
Which chains can be riveted with the Rohloff Revolver 2?
Any gear chains can be riveted with the Rohloff Revolver except 10 and 11-speed chains. Though, at any rate you should follow the manufacturer's instructions.
Instruction to 10-speed chains:
Because 10-speed chains have no projecting pins, the outer link plates lie flush with the pin ends. We recommend not to use the Rohloff Revolver 2 for riveting such a chain.
Shimano instructions to CN-6600:
The chain CN 6600 has to be exclusively opened and closed with the special riveting tools TL-CN23 and TL-CN32
Campagnolo products should never be mounted with foreign tools. The Campganolo tool "srl" is recommending for joining these chains.
Further information can be found on the website of the individual manufacturers.
Removal of the Rohloff sticker-tape with integrated series number - What is to be taken care of?
A general security advice: Each Rohloff SPEEDHUB 500/14 is provided with a running series number, which is placed on the sticker tape around the hub case.
Should the sticker-tape be removed (we definitely advise you not to do so), we recommend to use a sharp carpet knife to separate the series number from the other part and leave it on the hub. In case of a complete removal, you should keep the sticker-tape in whole, which you can stick e. g. onto the warranty card. Alternatively, the series number can be engraved on the hub case instead.
To each SPEEDHUB 500/14 and/or each bicycle, which is provided with a SPEEDHUB 500/14 in series, an orange warranty card is always enclosed.
This warranty card has to be
- filled in completely (including series number)
- stamped by an authorised dealer
- finally sent to the Rohloff AG, Mönchswiese 11, 34233 Fuldatal/Germany
This series number, only, gives necessary information about the year of production and is important for warranty claims and ownership.
Only with knowledge of the corresponding series number Rohloff is able to provide an optimal service.
We explicitly point out that the Rohloff AG grants no warranty or warranty claims for Rohloff SPEEDHUB 500/14 hubs without a valid series number!
Accordingly, any service, maintenance, repair, spare parts, etc. will be made on hubs only with an existing and valid (known to us) series number on the hub (or existing sticker-tape, warranty card, engraving).
