Shimano CS-M9200 XTR 12 Speed Micro Spline Cassette 

Ask mountain bikers what they need from their drivetrain, and the answer is universally simple: It needs to work. Nothing more. Nothing less.

Unlike more personalized components such as suspension, brakes, tires, and contact points, your drivetrain's mission move you forward while quickly and smoothly moving your chain up and down the cassette when shifting.

Yet, to consistently complete this critical assignment, many things must go right every time you push your thumb into the shift lever. And it’s that required consistency, durability, and robustness that separates SHIMANO drivetrains from all the rest.

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

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 load

10-51T wide ratio gearing allows a more efficient use of energy through finer cadence control in ever changing trail conditions

Sprockets are cut away extensively and drilled to further reduce weight without reducing rigidity

Sprockets use hard anodising and nickel-plated finish for added durability and resistance to corrosion

For use only with Micro Spline freehub bodies

Alloy cassette lockring
