Securing to the frame
What you can expect to find on this page
Here we explain our modular system. You will learn the basics for installing a SPEEDHUB in a bicycle.
There are basically three different versions of the RohloffSPEEDHUB 500/14. One with a quick relase axle (CC versions), one with a threaded axle (TS versions) and one with a 12mm Thru axle Frame compatible axle (A12 versions). The only other differences are with regards to the peripheral components.
The wide range of these components enable the Rohloff SPEEDHUB 500/14 to be mounted into nearly every type of bicycle frame.
The Rohloff SPEEDHUB 500/14 is available with different axle types. The CC versions come with a hollow axle for use with a quick release lever. The TS versions come with a threaded axle for use with standard M10x1 nuts for securing to the frame and the A12 version are for Thru Axle compatible frames. These are secured via 2x M7x1 bolts and special frame reduction sleeves inserted into the 12mm Thru axle dropouts.
The 14 gear mechanism on all versions is primarily the same.
The Rohloff SPEEDHUB 500/14 requires a frame spacing of 135mm, all frames with different frame spacing or for thru axles are not suitable for the Rohloff SPEEDHUB 500/14. The inner side of the left hand dropout must be flat in a diameter of 40mm around the center of the axle so that the axle plate can sit firmly and evenly against the dropout. There are different Rohloff SPEEDHUB 500/14 versions available (for the different dropout types) with the suitable axle and axle plate along with the corresponding parts for mounting. The Rohloff SPEEDHUB 500/14 is not available with an integrated brake mechanism. The frame must have the correct brake mounts to mount a rim or disc brake.
On frames with horizontal dropout slots, it is only possible to mount the Rohloff SPEEDHUB 500/14 in the TS threaded axle versions (TS and TS EX). The CC versions with a quick release lever will not hold the wheel secure enough and the wheel could be pulled crooked whilst riding.
When the slot lenght is shorter than 25mm (A), a chain tensioner (Art. #8250) must be fitted as there is not enough adjustment room within the slot to tension the chain.
The following versions of the Rohloff SPEEDHUB 500/14 are, therefore, suitable:
On frames with vertical dropout slots (C) the mounting of the Rohloff SPEEDHUB 500/14 normally suggests a CC quick release version (CC or CC EX). This as opposed to the TS versions (TS and TS EX) allows for a quicker wheel removal/installation without the use for Tools.
The following versions of the Rohloff SPEEDHUB 500/14 are , therefore, suitable:
* These versions must be used in conjunction with a chain tensioner (Art.No. 8250) except when an eccentric BB is being used.. The chain tensioner should be ordered with the initial product as it is not to be found in the regular package.
For frames with vertical dropouts and international standard disc brake mounts (IS 1999), the use of an OEM2 axleplate is highly recommended. With this, the disc brake mount will be used to secure the torque of the hub. Two mounting possibilities are to be decided between:
- Mounting with a disc brake on the rear wheel
The torque is secured through the Rohloff SPEEDBONE (Art. #8550), MonkeyBone (160mm= Art. #8553/ 180mm=Art. #8554), then through the disc brake mounts and secured tightly into the brake disc caliper.
- Mounting without a disc brake on the rear wheel
The Rohloff SPEEDBONE/MonkeyBone is not necessary. A support bolt secured through the lower disc brake mount can be used to support the torque.
Rigid frames with Rohloff OEM dropouts are specially designed for the mounting of all Rohloff SPEEDHUB 500/14 OEM versions. The long slot in the left hand dropout holds the support block of the OEM axle plate.
Frame types (F) have adjustable Rohloff OEM dropouts. With these dropouts on a hardtail frame, the need for a chain tensioner is eliminated because the wheel (once secured into the dropout inserts) can be pulled backwards to tension the chain. The dropout inserts are available from a variety of manufacturers with or without disc brake mounts and are all interchangable (supply information is available under www.rohloff.de). All Rohloff SPEEDHUB 500/14 OEM versions are suitable for these frame types.
Frame types (G) have unadjustable Rohloff OEM dropout and are specially designed for rear suspension models. A chain tensioner must be mounted, because the distance between the chainring and sprocket varies as the rear suspension is activated. All Rohloff SPEEDHUB 500/14 OEM versions are suitable for these frame types.
Requiremental for the OEM2 mouting of the Rohloff SPEEDHUB 500/14 with a support bolt is the position of the disc brake mounts. When the mount hole nearest the axle is behind a vertical line C up from the axle center (d 1), then the support bolt can be used. When the hole is in front of the vertical line C (d 2), then the use of the support bolt is not permitted.
