Leg length shims are used to increase effective the leg length on a shorter leg in cases where a cyclist suffers from a leg length discrepancy. Signs of a discrepancy can be:
a) overreaching on one side at the bottom of the pedal stroke
b) pelvis tilted or rider leaning to one side of the saddle in order to retain connection with the pedals through the bottom of the stroke
c) one leg feeling underextended whilst the other feels just right
Assuming the rider's position is correct, and their legs have been assessed to have a discrepancy, the issues above could be solved with the use of leg length shims. Shimming, with the correct amount of rise, can create a more equal leg extension, stabilise the pelvis and lead to a smoother and more controlled pedal stroke on the shorter side.
Universal 3-hole shims are compatible with Shimano SPDSL, Look style 3-hole and Time/Mavic pedals.
