Crank Arm Shortener

Decreases the pedal circle and therefore is suitable for people whose leg stretching is limited or those with unequal legs. If the leg’s movability is trainable, the adjustment of the crank arm shortener allows for gradual increase of the pedal circle and therefore optimized training results. For children in growth the crank arm shortener allows a continuous adjustment to their body size. Be sure to specify left leg/right leg, or both when ordering.
