The construction of the SPEEDHUB is based around a modular system. The classic 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 for fatbikes with 12mm thru axle system.
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 design. The Rohloff AG are pleased to offer 4 different methods of anchoring SPEEDHUB output torque to the bicycle frame, so that we remain compatible with nearly all dropouts styles available to a frame fabricator.
Further options; our ultimate goal is to retrofit as many bicycles as possible with a SPEEDHUB transmission. Two different gear mechanisms are thus available to help us achieve this goal. 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). The internal gear mech not compatible with disc brake versions.
