Shimano XTR CS-M9001 11-Speed Cassette

Features:

• Four Carbon Fibre carriers and 6 titanium sprockets make this Shimano's lightest 11-speed Dyna-Sys MTB cassette
• Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load
• 11-40T wide ratio gearing allows a more efficient use of energy through finer cadence control
• Four separate lightweight carbon fibre carriers reduce weight and increase stiffness giving more precise faster shifts
• 35/31/27/24/21/19T sprockets are all made from Titanium to reduce weight and increase durability
• Sprockets are cut away extensively and drilled to further reduce weight without reducing rigidity
• Nickel-plated finish offers hard wearing resistance to corrosion
• Alloy cassette lockring
• For use with 11-speed SIL-TEC chains
