SHIMANO XT M8100 12-Speed 10-45T Cassette

The SHIMANO DEORE XT CS-M8100-12 12-speed cassette delivers outstanding shifting performance. With new guide profiles for faster, smoother shifts thanks to HYPERGLIDE+ and BEAM SPIDER, this cassette features a lighter and stiffer construction that reduces inertia for quicker acceleration and improved chain stability. Using MICRO SPLINE technology, it includes a lowest 10-tooth (10T) sprocket designed around the new rear hub architecture, and this 12-speed drivetrain offers close-ratio wide-range gearing. The SHIMANO DEORE XT M8100 cassette, thanks to its BEAM SPIDER construction, ensures reduced weight while expanding the SHIMANO MTB range. The 10-45 and 10-51D cassettes, paired with the new SHIMANO MICRO SPLINE freehub body and HYPERGLIDE+ tooth profiling, deliver advanced shifting performance.
