Shimano SLX FC M7120-1 12 Speed Crank Arms



The Shimano SLX FC-M7120 1x12 cranks give a 55 mm chainline(3 mm further out than the FC-M7100) and is therefore suitable for frames with 148 mm over locknut dimensions. It is intended for leisure and training, less for racing. A direct mount system is used, which significantly speeds up chainring changes. In combination with a single ring with Shimano Dynamic Chain Engagement+ technology, FC-M7120 cranks ensure good chain retention, efficiency and low drivetrain noise.
