Shimano XTR Cassette 12 Speed 10-51T M9100

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 plus 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
• For use with Shimano 12-speed SIL-TEC chains
• Average weight 367g
