Shimano CS-M8100 12 Speed Cassette

Shimano Deore XT offers cutting-edge technology, lightweight with pro-level performance, but at a lower cost - meet the 12-speed superstar, CS-M8100-12

The Shimano Deore XT CS-M8100-12 cassette featuring Hyperglide+ technology comes with spider-mounted aluminum sprockets that offer low weight and supreme performance. Hyperglide+ gives near-silent shifts. Thanks to Hyperglide technology (HG), gear changes are crisp, smooth, and nearly silent. CS-M8100 cassettes feature an aluminum spider and an aluminum sprocket (the largest sprocket), which saves weight and contributes to durability. In addition, the Dyna-Sys system minimizes wear and optimizes power transmission. An incredibly versatile broad range of 11-45T and to an uber-cool 11-51T offers options for novice racers wanting to kill those steep rocks and mountains to those who want car-like comfort on every hill they encounter :)
