With the Shimano XT CS-M8100-12 cassette you can tackle every trail

With the Shimano XT CS-M8100 12-speed cassette you have the choice between a 10-45 t and a 10-51 t version. If you want to keep your gear jumps as low as possible, then the 10-45 gradation is the right one for you. If you want to cover as much range as possible, use the 10-51 option. Of course, all CS-M8100-12 cassettes feature Shimano Hyperglide+ technology for high shifting speed, precision and smoothness when shifting up or down. Noise is also minimised in this way. Weight reduction, robustness and durability are further enhanced by the aluminium spider construction and the two largest sprockets, which are also made of aluminium.

You'll get the support you need to master almost any terrain, while the propulsion system always provides you with the right shifting options to enjoy your ride untroubled.

Micro Spline
Micro Spline reduces the weight with a lightweight freehub, whereby the smallest sprocket
has 10 teeth. The ride stability is increased by 30 %. A 7.6° angle (max.) ensures fast response. Micro Spline freehubs can only be used in combination with Micro Spline cassettes and rear hubs.
