TerraCycle crank shortener
The crank shortener is an accessory designed to shorten the size of one of the cranks when, either because one leg is shorter than the other, or due to a different degree of knee flexibility, it is necessary to shorten that crank.
Two versions are manufactured, one for the left crank and another for the right crank.
