The Shimano XT CS-M8100 12-Speed Cassette features HYPERGLIDE+ technology for improved shifting efficiency across the gear range. Its construction reduces weight while extending the MTB gearing options. Available in 10-45T and 10-51T configurations, it is designed for demanding trail conditions.
This cassette requires a Shimano MICROSPLINE freehub for installation. The 10-speed cog provides ample speed for descents, while the larger cogs support climbing on steep trails. The 10-51T option is for single chainring setups, and the 10-45T is compatible with single or double chainring configurations.
