Abstract
The crank arm of a bicycle is selectively shortened by removing the pedal and attaching one end of the shortener to the pedal opening in the crank arm, with the other end of the shortener being locked to the crank arm by a pair of cams positioned against opposite side edges of the crank arm. Rotation of bolts through the eccentrically mounted cams causes the cams to snugly engage the crank arm side edges to lock the shortener to the crank arm.
