Specialized Body Geometry Cleat Stackers

Cleat stackers are specifically designed to address leg length discrepancies. If you experience persistent hip pain, knee discomfort, or notice uneven wear on your cleats despite a proper bike fit, you may have a functional or anatomical leg length inequality that these stackers can help correct.
