Shimano's new XT-level 10-speed cassette specifically designed to work with a 10 speed drivetrain. Shimano developed Dyna-Sys with the goal of increasing rider efficiency. This means closer ratios, smoother shifts, and a more stable pedal stroke. Compatible with 8/9/10 speed free-hub bodies, requires use of a 10 speed chain, and comes with an alloy lock ring. Gear ratio 11t – 36t
