What cassette does Shimano Deore XT M8000 use?

The CS-M8000 is the 11-speed cassette for Shimano's Deore XT M8000 groupset, built with Hyperglide shift ramps and tooth profiles optimized for the XT tier's trail and enduro riding demands. The 11-40t range covers everything from fast fire road descents to steep technical climbs on a single chainring without compromise. XT-grade construction means tighter tolerances, better wear resistance, and more consistent shifting over the life of the cassette compared to lower-tier options.

Compatible with Shimano Deore XT M8000 and other Shimano 11-speed MTB drivetrains. Fits standard HG freehub bodies. Requires a Shimano 11-speed MTB Hyperglide chain. The benchmark cassette for serious trail riders on 1x11 builds.

FAQ

How does the 11-40t differ from the 11-42t XT cassette?: The 11-40t offers tighter gear steps and slightly less low-end climbing range compared to the 11-42t. Riders who prioritize cadence consistency over bailout climbing gear typically prefer the 11-40t.

Is this cassette compatible with all Shimano 11-speed MTB drivetrains?: Yes. The CS-M8000 uses the standard Shimano HG splined freehub body and is compatible with all Shimano 11-speed MTB drivetrains.

What chain is recommended?: Use a Shimano 11-speed MTB chain such as the CN-HG700, CN-HG701, or XTR CN-M9000 for optimal shifting performance.

Best For

XC racers, marathon riders, and trail riders running Shimano XT 11-speed who want a tighter-range cassette with closer gear steps for cadence efficiency on rolling and moderately climbing terrain.
