With its beam spider construction, the new Shimano Deore XT M8100 12 Speed Cassette shaves weight while increasing Shimano's MTB gearing range another gear. Using Shimano's new micro spline freehub body and hyperglide+ tooth profile, these 10-45 and 10-51T cassettes deliver advanced shifting performance.

Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load.
