Shimano XTR M9100 Cassette 12 speed 2025

With this XTR M9100 12 speed Shimano offer its most advanced cassette. To build it Shimano has developped a brand new technology named Hyperglide+ that provides faster, quieter and smother shifts while pedaling. The brand has carefully selected materials to provide the better weight to resistance ratio so small sprockets are in steel, centrals are in titanium and 3 bigs are in aluminium. To install this M9100 cassette on your wheel they also designed a new aluminium driver body named Micro Spline that's more resistance but not many brands have licensed this freehub for now.
