Shimano SM-SH20 Cleat Spacer and Fixing Bolt

The SM-SH20 spacer is designed to help riders fine-tune their cleat position for better biomechanical alignment. It is most commonly used to address leg length discrepancies or to achieve a more natural foot angle for improved pedaling efficiency and comfort.

You might consider a spacer if you experience discomfort, uneven pressure, or knee pain that suggests your leg length or foot angle isn't perfectly supported by your current setup. Many riders use them after a professional bike fit identifies a need for minor adjustments to cleat stack height or canting.

While the SM-SH20 is designed to provide a specific amount of clearance, stacking multiple spacers is generally not recommended as it can compromise the security of the cleat-to-shoe interface. If you require significant height adjustment, it is best to consult a professional bike fitter to explore other solutions.
