The Shimano XT FC-M8100-1 crank provides a smoother ride

The FC-M8100 12-speed XT crank from Shimano produces a chainline of 52 mm when ridden with a single chainring, and is suitable for frames with both 142 mm and 148 mm over locknut dimensions. The crank is based on a direct-mount system, which ensures a quick chainring change. Combine it with a Shimano Dynamic Chain Engagement+ chainring with a high-precision tooth profile (not included) and you get a front drivetrain of the highest efficiency and low noise that guarantees good chain retention. The stiff and light design of the FC-M8100 with its hollow-forged crank arms helps to increase fun and efficiency on any kind of trail. By the way, the crank can also be fitted with two chainrings, resulting in the model FC-M8100-2 for 48.8 mm chainline.

Technology:

Hollowtech II
Shimano Hollowtech II is a crank bottom bracket system designed to achieve an ideal ratio of stiffness, weight and rotational efficiency. It is based on an integration of the bottom bracket and the right crank arm and works with a 24 mm axle or bearing diameter, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside so that the load is better distributed. High-quality precision seals ensure a long service life.
