Shimano XTR CS-M9100 Cassette Info
The Shimano XTR CS-M9100 Cassette sits at the top of Shimano's mountain bike drivetrain lineup — a 12-speed cassette engineered to deliver clean, consistent shifts under load. The cog construction is deliberately tiered: aluminum outer cogs keep weight down, titanium mid cogs balance strength where pedaling forces are highest, and steel inner cogs handle the sustained demands of climbing and low-cadence power. The result is a 370g cassette that doesn't ask you to choose between durability and weight savings.
The wide-range gear spread — available in 10-45 or 10-51 configurations — covers everything from technical singletrack climbs to fast descents. One important compatibility note: this cassette requires a Shimano Microspline freehub. It is not compatible with standard HG or XD driver bodies, so verify your hub before ordering.
