Product Description The Shimano SLX FC-M7100-1 cranks - an efficient, safe drivetrain The Shimano SLX FC-M7100 12-speed crank produces a chainline of 52mm when ridden with a single chainring. It is based on a direct-mount system, which significantly speeds up chainring changes. In combination with a single chainring that has Shimano Dynamic Chain Engagement+ technology (not included), good chain retention, efficiency and low noise are guaranteed. Hollow-forged crank arms reduce weight while providing highly-efficient power transmission. The FC-M7100 crank was designed for leisure and training, not so much for racing. It can also be fitted with two chainrings, resulting in the model FC-M7100-2 for a 48.8 mm chainline.

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.
