Shimano Deore HG-M6100 12-Speed Cassette

The Shimano Deore CS-M6100-12 Cassette is built for mountain bikers who demand fast, precise, and reliable shifting — even under load, on the most demanding trails. Designed as part of the DEORE M6100 groupset, it pairs exclusively with a MicroSpline freehub body, ensuring seamless compatibility with 12-speed drivetrain setups.

Powered by Hyperglide+ technology, every shift — whether up or down — is executed with remarkable smoothness, maintaining power transfer without interruption. No more hesitation in technical climbs. The BEAM SPIDER construction reduces weight while increasing chainring rigidity, delivering sharper acceleration and a more immediate pedal response when it matters most.

With a gear range spanning 10 to 51 teeth (10-12-14-16-18-21-24-28-33-39-45-51T), this cassette covers an exceptional spread of gearing to handle everything from steep climbs to fast descents. Its 12 steel and aluminium sprockets strike the ideal balance between durability and weight, coming in at just 595 g.

Compatible with the CN-M6100 12-speed chain and 1x chainring systems, the CS-M6100-12 is the go-to cassette for any rider looking to unlock the full potential of their mountain bike.
