FORM MTB Leg Length Shim – Walkable V2

Description FORM’s patented MTB Leg Length shims are the only “walkable” MTB shim on the market and were developed specifically to overcome the issues inherent in traditional MTB shim designs.  These shims are ideal for gravel, cyclocross or cross-country MTB riding where a relatively high amount of time is spent in seated pedaling, and are best suited to traditional MTB, gravel, or touring shoes utilizing an MTB or SPD style (2-hole) cleat. Why Standard MTB Leg Length Shims Cause Problems Difficulty when walking or clipping in A wobbly and unstable connection to the pedals Key Features of the Walkable V2 Shim 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 When and Why to Use a Mountain Bike Leg Length Shim Leg length shims are used to increase the effective leg length of 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 to retain connection with the pedals (many times this is apparent in saddle wear on one side more than the other) One leg feeling under-extended whilst the other feels just right Assuming a rider has been assessed to have a discrepancy, the issues above could be solved with the use of leg length shims.

Look X-Track Which MTB Shoes are Compatible with the V2 MTB Shim? Although the V2 Mtb shim works with many brands and models of MTB shoes, it does not work with absolutely everything. Sometimes the shoe or shim can be modified with careful removal of interfering material and be made to work, and sometimes it doesn’t.  Shoes at the small end of the size range present more challenges than larger shoes, due to the reduced length of the sole and shape and position of the lugs. The dimensions of the shim that go between the treads are 37.5mm wide x 62mm long, and you want a flat surface for this area to sit on. If you find the shim kit is not compatible with your MTB shoes, contact us to request a return and refund. Installation Instructions Click here for installation instructions
