Shimano SLX M7100 12-Speed Micro Spline Cassette

Trail-Tested Performance, Every Shift.

The Shimano SLX M7100 12-Speed Micro Spline Cassette brings proven trail performance and precision shifting to your setup — durable, efficient, and built to deliver reliable performance ride after ride.

Its Hyperglide sprocket design features computer-optimised tooth profiles and contoured shift gates for fast, smooth gear changes, even under load. Whether you’re powering up steep climbs or pushing through rocky descents, this cassette keeps your cadence tight and your energy output efficient.

Engineered for Real Riders

A lightweight, minimal-design sprocket carrier keeps weight down while maintaining the stiffness you need for responsive shifting. The sprockets are cut away and drilled to further reduce grams without compromising rigidity, making the M7100 a workhorse that feels quick, precise, and ready for anything the trail throws at it.

Built to handle the demands of modern 12-speed drivetrains, it pairs perfectly with 12-speed MTB chains and Micro Spline freehub bodies for a clean, secure fit.
