SHIMANO CS-M8100 CASSETTE 10-51T XT

The XT CS-M8100 12 Speed Cassette offers the excellent shifting performance that we have come to love from Shimano in both Wide Range and Rhythm step options. Both cassettes feature Beam Spider technology for increased weight savings, rigidity and durability. They also feature the Hyperglide+ technology found in XTR, offering Shimano's smoothest ever shifts in a lightweight package.

The 10-51T Wide Range cassette is perfect for riders after a huge range on their 1x set up. It offers a 510% range with smart gear steps for the ultimate climbing machine.
