The Shimano XT M8100 series cranks are built to handle everything you can throw at them. By utilising Hollowtech II technology Shimano is able to keep the weight down, while still creating a rigid crank arm capable of handling some seriously aggressive trail riding.

The M8100 cranks are compatible with both Boost and non-Boost frames. Also check out the M8120 cranks for the Boost only version.
