Building on the experiences of the world's best mountain bike racers, Shimano has brought its race-winning technology to competitive and enthusiastic mountain bike riders.
The new DEORE XT M8100 series, the latest iteration of the original MTB groupset, continues its legacy with high performance features for today's demanding and adventurous mountain bikers.

The new XT 1x12-speed cranks are characterised by DYNAMIC CHAIN ENGAGEMENT+ technology, whose special high-precision tooth profile ensures that the chain finds optimum grip on the upper part of the chainring on rough terrain, but detaches equally well from the chainring at the bottom, thus ensuring efficiency, smoothness and low noise of the drive. The cranks are equipped with a direct-mount system for quick and safe assembly of the chainrings, enabling chainrings to be changed in no time at all. The crank is available in boost and non-boost specifications.
