Shimano CS-M9101 XTR 12-speed cassette 10 - 51T
XTR - the top of the range Shimano 12-speed mountain bike cassette
Constructed from alloy 5 beam spider carrier with 3 alloy, 5 titanium and 4 Chromoly sprockets make this a lightweight, stiff and durable 12-speed Micro Spline MTB cassette
Shimano's Hyperglide+ sprockets have a computer designed tooth configuration with contoured shift gates, resulting in 1/3 faster shift time than current HG cassettes providing seamless, smooth operation even under heavy loads
10 - 51T wide ratio gearing allows a more efficient use of energy through finer cadence control - even in changing conditions
Sprockets are cut away extensively and drilled to further reduce weight without reducing rigidity, and made from hard anodising and nickel-plated finish for added durability and resistance to corrosion.
Alloy cassette lockring
For use with Shimano 12-speed SIL-TEC chains and only with Micro Spline freehub bodies
