The Deore CS-M6100 12 speed cassette offers the same outstanding performance of Shimano's higher-end 12-speed cassettes at a fraction of the price. The cogs are all steel and mounted to an aluminium Beam Spider to keep things nice and rigid and the weight as low as possible. The cassette features Shimano's Hyperglide+ technology to provide smooth and precise up and down shifts, even while under load. 

Available in 10-51t and compatible with Microspline freehubs only.

Who's this item for: This cassette is recommended for use with the Deore M6100 drivetrain but it's a great choice for anyone that running a Shimano 12 speed setup and needs to replace their cassette.

Number of gears: This is a 12-speed cassette.

Weight: Approx 593g.

Materials / construction: 12 steel cogs with the largest 3 mounted on the Beam Spider.

Cog-tooth span: This cassette is available in 10-51t only.
  • 10-51: 10-12-14-16-18-21-24-28-33-39-45-51T
Freehub mounting style: Mounting is via the Microspline system.

Other component compatibility: Cross-compatible with other Shimano 12 speed drivetrains. Only compatible with Microspline freehubs.

Pros: All the same technology and shifting performance as you'd find on Shimano's top-end offerings at a fraction of the price.

Cons: The cassette is all steel, without any alloy cogs so there is a bit of a weight penalty but not too much. It's only 60-70g heavier than the SLX cassette.
