1 reviews for Shimano XT CS-M8100 cassette 12-speed Microspline with an average rating of 5/5 points.
Huge range and the best shifting cassette I've ever used. Very well made cassette, slightly heavy but worth the penalty due to the very smooth shifting and range of gears. Combined with the XT mech & Hyperglide chain the shifting is the best I've used. Smooth and precise even under heavy shifting. ★★★★★ Steve Davies
