Shimano Deore XT CS-M8100 12s 10-51T Cassette

The Shimano Deore XT CS-M8100 12-speed cassette is optimized for MTB excellence. With rider-tuned wide range and close step gear combinations, shift ramp designs provide fast and smooth shifts with HYPERGLIDE+ technology.

The CS-M8100 cassette is designed with a Shimano Micro Spline body that features smaller and more widely distributed splines to limit cog damage on freehub. Light and stiff construction reduces cassette inertia resulting in faster acceleration and increased chain security. It also meets durability requirements for E-MTB applications.
