Shimano XTR M9000 11 Speed Cassette: 11-40T
Shimano XTR M9000 11 Speed Wide Range Cassette: 11-40T
The Shimano M9000 cassette is precisely engineered to perform in conjunction with the rest of the XTR drivetrain for next level performance on the trail. The cog sizes are based on Shimano's Rhythm Step Progression to provide smooth shifts from gear to gear to help you keep your rhythm on the trail, and thereby keeping your speed up, too. A carbon fiber spider holds onto the 40T anodized aluminum big cog, and the following six cogs are made from titanium to shave weight while the remaining small gears are constructed from durable nickel-plated steel.
