Overview
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
Good questions
Get to know Shimano

There's more to Shimano than this one product. Our Shimano page has the full Shimano lineup we carry and more about the brand.
Visit the Shimano page →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.
