The Shimano SLX FC-M7120-1 Crank – Higher safety and efficiency

Shimano’s SLX FC-M7120 12-speed crank produces a chainline of 55mm when ridden with a single chainring. This is 3 mm further out than with FC-M7100-1, which makes the crank is especially suitable for frames with 148 mm over locknut dimension. A direct-mount system is used, which significantly speeds up the process of changing the chainring. 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 the most efficient power transmission.
