Shimano XTR CS-M9000 Cassette
Shimano XTR CS-M9000 Cassette Info
The Shimano XTR CS-M9000 Cassette is built from a deliberate mix of materials — aluminum, titanium, carbon, and steel — each placed where it earns its keep. The 40t cog is aluminum to keep weight down at the largest, most weight-sensitive end. Moving inward, the mid-range cogs from 35t to 19t are shot-peened titanium, balancing durability with a weight profile that suits hard trail riding. The four smallest cogs — 17t through 11t — are shot-peened, nickel-plated steel, prioritizing the longevity you need in the gears you use most.
The larger cogs mount to carbon fiber spiders, while the next grouping uses anodized aluminum spiders — a structure designed to minimize weight without compromising the rigidity that clean shifting depends on. With an 11-40t range across 11 speeds, this cassette covers serious climbing terrain while still giving you the top-end gearing for fast cross-country riding. It fits any standard 10- or 11-speed Shimano-compatible freehub body, so upgrading your drivetrain doesn't require new wheels.
