The construction of the SPEEDHUB is based around a modular system. The original SPEEDHUB versions are constructed for a 135mm O.L.D. and available with a choice of quick-release (CC) or threaded axle (TS). In the past years, the Rohloff AG have extended the SPEEDHUB range to remain compatible with modern, alternative mounting options. As such, we are pleased to confirm that SPEEDHUBs are currently available to fit numerous frame spacings from 135mm to 197mm.

|CC (Hollow axle)||✘||✘||✘|

Regardless whether you wish to decelerate with rim or disk brakes, the SPEEDHUB can be used with either system. Rim brake specific versions are supplied with a smooth, polished hub cap, whereas disc brake versions are supplied with a hub-cap incorporating a 4-hole brake rotor mount.
One of three main axle types are used on bicycles nowadays. The classic 10mm threaded axe, the 10mm quick release axle and the 12mm thru-axle. SPEEDHUBs are available to fit in bicycle frames using each of these 3 systems.
Torque anchoring apparatus
Frame construction is an art-form. As with every art form, the artist/fabricator wishes to leave their signature and this is often achieved through the dropout form. The Rohloff AG are pleased to offer 4 different methods of anchoring SPEEDHUB output torque to the bicycle frame, so that we can remain compatible with near all dropouts form selected by the frame fabricator.
Further options. Our ultimate goal is to retrofit as many bicycles as possible with a SPEEDHUB transmission. Two different gear mechanisms are therefore available to help us achieve this. An internal gear mech which sits inside the dropouts, directly on the gear-unit, and an external gear mech where a cable box is located outside of the dropout away from brake rotors (internal gear mech not compatible with disc brake versions).[
