Shimano CS-M9100 XTR 12-Speed Cassette
Product Details
The Shimano CS-M9100 XTR 12-Speed Cassette delivers elite-level shifting performance, lightweight construction, and an expanded gear range for aggressive mountain bike riding. Engineered with Shimano’s advanced BEAM SPIDER construction, this cassette reduces weight while increasing drivetrain efficiency, giving riders smoother, faster shifting across technical terrain.
At the core of the design is Shimano’s HYPERGLIDE+ tooth profile, developed to improve chain engagement and deliver exceptionally smooth shifting under load. Better chain retention and smoother pedaling inspire confidence on steep climbs, rapid descents, and constantly changing trail conditions. The 10-45T gear range provides a balanced setup for riders seeking tight gear progression without sacrificing climbing capability.
Constructed using a strategic blend of aluminum, titanium, and steel, the XTR M9100 cassette balances weight savings, rigidity, and long-term durability. Compatibility with Shimano’s MICRO SPLINE freehub body allows for a lightweight aluminum interface and a compact 10-tooth smallest cog, maximizing gearing efficiency and drivetrain performance. Compatible with Shimano Hyperglide+ chains, this cassette is built to deliver the highest level of MTB shifting precision.
