Shimano Deore XT CS-M8100 12-Speed Cassette (10-45T / 10-51T)

Upgrade your drivetrain with the definitive performance of the Shimano Deore XT CS-M8100 12-Speed Cassette. Featuring advanced BEAM SPIDER construction, this mountain bike cassette sheds weight while expanding Shimano's gearing range. Utilizing the innovative MICRO SPLINE freehub body and HYPERGLIDE+ tooth profile, it delivers incredibly smooth, fast, and precise shifting. Highly versatile, it is perfectly suited for demanding MTB trails and is also fully compatible with the new Shimano GRX gravel systems.

Key Features

HYPERGLIDE+ Shifting: Features completely redesigned shift ramps that provide the fastest, smoothest shifting up and down the cassette, even under extreme pedaling forces.
BEAM SPIDER Construction: A lighter and stiffer design that significantly reduces cassette inertia, resulting in faster acceleration and enhanced chain security on rough terrain.
MICRO SPLINE Technology: An innovative freehub body construction that seamlessly enables the use of a 10T lowest sprocket for a massive overall gear range.
Wide Range & Close Steps: Choose between the close-step 10-45T for finer cadence control or the ultra-wide 10-51T for conquering the steepest climbs.
