Shimano SLX FC-M7100 Left Crank Arm This genuine Shimano replacement left crank arm restores the original fit and function of a compatible SLX FC-M7100 chainset. It is intended for workshop repair where the left arm is worn, damaged or requires replacement. The selected length length must match the right-hand crank arm to maintain balanced pedalling geometry. Using unequal crank lengths can affect rider position, pedalling action and component clearance. As an original Shimano service part, it retains the correct axle interface and fastening arrangement for the stated chainset. Exact model and length verification is required before purchase.
