Shimano Cleat Spacer

This spacer is designed to provide a 1.0 mm adjustment to your cleat setup. It helps riders achieve better contact between their shoe and pedal, which can improve power transfer and address minor alignment issues.

This spacer is specifically designed for standard SPD cleat systems, including SM-SH51 and SM-SH56 cleats. It is not compatible with SPD-SL or other road-specific cleat systems.

While it is technically possible to stack spacers, we generally recommend consulting with a professional bike fitter first. Stacking too many can compromise the integrity of the cleat bolts and may prevent the cleat from engaging securely with the pedal.

In most cases, the standard bolts included with your cleats are sufficient for a single 1.0 mm spacer. However, if you find that you have less than 5mm of thread engagement after installation, you should switch to longer mounting bolts to ensure safety.

You might need a spacer if you experience uneven pressure on your pedals, difficulty clipping in, or if you are trying to correct a slight leg length discrepancy or foot alignment issue. If your cleats feel loose or you feel 'hot spots' on your feet, a spacer can sometimes help optimize your interface.
