Shimano CS-M9001 XTR 11-speed cassette 11 - 40T
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
