SHIMANO DEORE XT m8100 - 12-Speed - HYPERGLIDE+ - MTB Cassette Sprocket With its BEAM SPIDER construction, the new SHIMANO DEORE XT M8100 12-speed cassette shaves weight while increasing SHIMANO's MTB gearing range another gear. Using SHIMANO's new MICRO SPLINE freehub body and HYPERGLIDE+ tooth profile, this 10-51T cassette delivers advanced shifting performance. The Shimano XT CS-M8100 12-speed cassette is available in 10-45 t and 10-51 t versions. If you are looking for the lowest possible amount of gear steps, then the 10-45 tooth version is a good pick. If you want to cover as much bandwidth as possible, then opt for the 10-51 tooth version. Of course, all CS-M8100-12 cassettes feature Shimano Hyperglide+ technology for high shifting speed, precision and ease in up-/down-shifting. This has the added benefit of minimising noise. The spider as well as the two largest sprockets are made of aluminium, which contributes to weight reduction, robustness and durability.
