BikeFit Leg Length Shims

If you experience consistent knee, hip, or lower back pain on one side while cycling, or if a professional bike fit has identified a functional or structural leg length discrepancy, these shims can help. They are designed to level your pelvis and improve your pedal stroke efficiency by compensating for that difference.

These shims are specifically designed for the Wahoo Speedplay four-hole cleat system. They are not compatible with standard three-hole road cleats, so ensure your shoes are drilled for the four-hole pattern before purchasing.

Yes, you can stack these shims to achieve a greater height adjustment. However, if you are stacking more than two shims, you will likely need to source longer mounting bolts to ensure the cleat remains securely attached to the shoe.

No, these shims are designed to sit between the shoe sole and the cleat base plate, so they do not interfere with the engagement mechanism or the float characteristics of your Speedplay pedals.

The high-density plastic is engineered to be durable and rigid, providing a stable platform that resists compression under the high loads of pedaling. It is designed to maintain its shape and thickness over time, ensuring your fit remains consistent.

Yes, the shims are molded with a slight curvature to conform to the natural arc of most cycling shoe soles. This ensures a flush, secure interface between the shoe and the cleat, preventing any rocking or instability.
