Specialized Body Geometry Cleat Stacker

If you experience consistent knee, hip, or lower back pain on one side while riding, you may have a functional or structural leg length discrepancy. A professional bike fit is the best way to confirm this, but many riders notice the need when their saddle height feels correct on one side but uncomfortable on the other.

These are designed to work with most major road and mountain bike cleat systems, including Look KEO, Shimano SPD, and Speedplay. However, because cleat bolt patterns vary, you should verify that your specific cleat hardware allows for the extra 3mm of stack height without compromising bolt engagement.

While you can technically stack them, it is generally not recommended to exceed 3mm without consulting a professional fitter. Adding too much height can interfere with the security of your cleat bolts and may require longer mounting screws to ensure the cleat remains safely attached to your shoe.

No, this pack contains only the 20 stackers. You will need to source longer cleat bolts separately to accommodate the additional 3mm of thickness, as your standard factory bolts will likely be too short to safely secure the cleat.

This bulk pack is primarily intended for professional bike fitters or riders who maintain multiple pairs of cycling shoes. It offers a cost-effective way to keep a supply on hand for ongoing adjustments or to outfit your entire rotation of footwear.
