Shimano XT FC M8120-1 Crank Arms 12-Speed



The Shimano XT FC-M8120 1x cranks, unlike the FC-M8100-1 cranks, produce a chainline of 55 mm, so a 148 mm rear hub is recommended. It is based on a direct mount system that significantly accelerates chainring changes. In combination with a Shimano Dynamic Chain Engagement+ chainring, you get a front drivetrain of the highest efficiency and low noise, which also provides good chain retention.
