When I shop for the Shimano SM-SH51 SPD pedal cleat set, I focus on fit, durability, and ease of installation. I want a cleat that works smoothly with my SPD pedals and gives me a secure connection without making unclipping difficult. The included 4mm Allen wrench is also a nice bonus because it saves me from hunting for the right tool.
Compatibility with My Shoes and Pedals
