The Shimano XT FC-M8120 1x12-speed Boost crank


Made in Japan


The crank with 178 mm Q-factor, 55 mm chainline and 148 mm boost stands for highest drive efficiency at low weight. It offers optimum power transmission and maximum speed for the new XT system, which only use 1 chainring.


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.


The original mountain bike group continues its legacy of remaining the standard for mountain bikers everywhere. Nearly three decades in, the DEORE XT brand is defined by its trail-tested durability, reliability and performance. Recognizing that today’s mountain bikers are riding faster and confidently on more technical terrain, the legacy of DEORE XT is more important than ever. In 2019, our pinnacle mountain bike technologies will trickle down to SHIMANO DEORE XT M8100.
