Shimano Deore XT M8100 12-Speed Cassette. Micro Spline 10-51T

The Shimano Deore XT M8100 12-Speed Cassette provides smooth shifting and large 10-51T gear range at an affordable price. This cassette uses a Beam Spider for a stiffer construction while reducing the inertia needed to rotate the gears. An updated shift ramp paired with Hyperglide+ technology provides smooth and fast shifting. Built around a Micro Spline freehub body, the Shimano XT M8100 cassette uses a 10T cog and offers an impressive 510% gear range.

Micro Spline Freehub
