MICRO SPLINE FREEHUB System

Designed specifically for SHIMANO’s 12-speed XTR drivetrain, the MICRO SPLINE FREEHUB delivers a lightweight construction that works seamlessly with the system’s new small 10-tooth cog. As the name suggests, MICRO SPLINE features smaller freehub splines that help eliminate damage on the lightweight aluminum freehub. 

 

The new hubs also feature SHIMANO’s quieter SCYLENCE technology that provides rapid acceleration and higher rigidity for quick, 7.6-degree engagement. The freehub body is constructed of two driver plates that completely disengage when you stop pedaling, eliminating any freehub ratchet sounds while coasting.
