Dropout types

Horizontal Dropout Slots < 25mm

It is only possible to mount the Rohloff SPEEDHUB 500/14 into frames with horizontal dropout slots, using TS threaded axle SPEEDHUB models (TS & TS EX). The CC versions using quick release skewers will not hold the wheel tight enough to avoid it moving when pedaling hard and should therefore not be used. If the dropout slot is shorter than 25mm, then an external Chain tenioner (Art. #8250) should be mounted as the dropout does not incorporate enough room to accommodate the axle, tension the chain and allow for adjustment as the chain wears. The following versions of the Rohloff SPEEDHUB 500/14 with a long torque arm are therefore suitable:

  • TS
  • TS EX


Horizontal Dropout Slots > 25mm

It is only possible to mount the Rohloff SPEEDHUB 500/14 into frames with horizontal dropout slots, using TS threaded axle SPEEDHUB models (TS & TS EX). The CC versions using quick release skewers will not hold the wheel tight enough to avoid it moving when pedaling hard and should therefore not be used. If the dropout slot is longer than 25mm, then an external Chain tenioner (Art. #8250) is not required. The dropout slot is long enough to accommodate the axle, tension the chain and allow for adjustment as the chain wears. The following versions of the Rohloff SPEEDHUB 500/14 with a long torque arm are therefore suitable:

  • TS
  • TS EX





Vertical Dropout Slots

On frames with vertical dropout slots (C) the mounting of the Rohloff SPEEDHUB 500/14 normally suggests a CC - hollow, quick release axle version (CC or CC EX). This, as opposed to the TS versions, offers a faster wheel removal/installation without the need for tools. The dropout shape 'C' will require the additional use of an external Chain tensioner or (if this is a hardtail frame) an EBB (eccentric bottom bracket) in order to keep the chain correctly tensioned as components wear. The following versions of the Rohloff SPEEDHUB 500/14 with a long torque arm are therefore suitable:

  • CC
  • CC EX
  • TS
  • TS EX



Equipped with disk brake mounts of International Standard (IS 2000)

Frames (D) equipped with International Standard (IS 2000) disk brake mounts, can use an OEM2 axle plate for anchoring the torque of the SPEEDHUB. Alternatively, the version with the long torque arm could be used (like on frame type C) however is not the cheapest, nor most aesthetically pleasing of variants.

Frames using dropout shape (D) will require the additional use of an external Chain tensioner or (if this is a hardtail frame) an EBB (eccentric bottom bracket) in order to keep the chain correctly tensioned as components wear

ATTENTION:
For safe OEM2 mounting with either a support bolt, a Rohloff SPEEDBONE or the Monkeybone, the following points must be well noted:

The disc brake mounts must be one piece with the dropout itself, be of International Standard (IS2000) and have the following minimum dimension requirements: The minimum thickness of material used must not be less than 6 mm. 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 (d1), 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.

Frames equipped with a 'Horst Link'

Frame type (E) is equipped with a Horst Link. Mounting a SPEEDHUB into a frame like this is only possible if the dropout includes an International Standard (IS2000) disc brake mount. If so, a SPEEDHUB can be fitted using an OEM2 axleplate. All Rohloff SPEEDHUB 500/14 versions can be mounted on this frame type as long as they are fitted with this OEM2 axle plate.

A chain tensioner must be mounted on these (E) full suspension frames as the chainstay length alters during use.

OEM Dropouts

Frame type (F) has adjustable Rohloff OEM dropouts. When used on a rigid frame, these OEM dropouts integrate a method of chain tensioning into the frame, eliminating the need for an additional external chain tensioner. These dropout inserts are available from a variety of manufacturers both with or without disc brake mounts.

 

Both OEM and OEM2, CC and TS SPEEDHUB versions can be mounted into these dropouts.


OEM Dropouts for rear suspension bikes

Frame types (G) have fixed position Rohloff OEM dropouts. These can be found on hardtail frames where an excentric BB is used to tension the chain but are most commonly found on rear suspension frames. An external chain tensioner must be fitted to such bicycles because the distance between the chainring and sprocket varies as the rear suspension is activated.

 

Both OEM and OEM2, CC and TS SPEEDHUB versions can be mounted into these dropouts.
