Description

Leg length shims are used to increase the effective leg length on a shorter leg in cases where a cyclist suffers from a leg length discrepancy. Signs of a discrepancy can be:

overreaching on one side at the bottom of the pedal stroke
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
one leg feeling under-extended 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.

In some cases shims can be used to solve a functional leg length difference. This is when a rider has no physical difference in leg length, but shows a marked difference in leg extension when riding. In cases like these it’s always advisable to see a bikefitter first, prior to making assumptions about what is required.

Technical info

FORM’s patented MTB shims are the only “walkable” MTB shim on the market, and were developed specifically to overcome the issues inherent in traditional MTB shim designs, those being;

- a difficulty when walking or clipping in

- a wobbly and unstable connection to the pedals

FORM's product solves these issues by using:

- 2 parallel tread areas to protect the cleat and add clipped in stability

- chamfered front feet which facilitate easy cleat engagement

- two sets of posts/tabs which protrude into the shoe to resist rotation

These shims are ideal for gravel, cyclocross or cross country MTB riding where a relatively high amount of time is spent in seated pedalling, and are best suited to traditional MTB, gravel, or touring shoes utilising an MTB style (2-hole) cleat.

The V2 shim is compatible with all MTB style cleats, including SPD, Time ATAC, Crank Bros.

The V2 shim is also compatible with the new FORM extra tall MTB stacker kits.

Kit includes: 3mm main body / cleat plate / 2mm stacker / 1mm spacer / screws

* Please contact us if you use Look X-Track. These are also compatible but require a different bolt.
