SRAM SRAMI-MOTION 9 FREEWHEEL BRAKE INTERNAL GEAR HUB

The SRAM i-MOTION 9 freewheel opens up new possibilities where trekking is concerned. You’re always in the right gear, whether you’re cycling uphill or downhill. With perfect, almost continuous gear ratios between 14% and 17%, the 9 speed-gear hub is not only a step ahead of other conventional 8 speed-gear hubs, the i-MOTION 9 is also much more harmoniously adjusted.
