Small details make a big difference especially when it comes to mountain biking. Worn out cleats can lead to poor pedal function including premature or stubborn release. But swap on a new set of Shimano SM-SH51 Cleats and you know they're purpose built to work seamlessly with nearly all Shimano SPD Pedals, delivering long lasting performance thanks to their heat treated forged steel construction that will stand up to even the harshest riding conditions.
