Know before you buy
Single release means you can only unclip your shoe by twisting your heel outward. This provides a consistent, predictable motion that many cyclists prefer for stability.
These are designed specifically for Shimano SPD-style pedals. They will not work with SPD-SL (road) pedals or other proprietary systems.
The SH51 is a single-release cleat, meaning it only releases in one direction. The SH56 is a multi-release cleat that allows you to unclip by twisting your heel in multiple directions, which is often preferred by beginners.
Yes, the set includes the cleats and the required mounting hardware to attach them to your cycling shoes.
You should replace your cleats when you notice the metal becoming visibly worn or if you feel the engagement with your pedal becoming loose or inconsistent. Worn cleats can lead to accidental unclipping while riding.
