Shimano SPD Cleat Set – SM SH51

The Shimano SM-SH51 is a single directional release type SPD cleat set used for mountain biking and city riding purposes. The Shimano SM-SH51 cleats are specially cold-forged and heat-treated to increase durability and rigidity for heavy use even under severe conditions. The SM-SH51 cleats can only be used with mountain or touring pedals (SPD). The release mechanism of SH51 can be achieved by twisting the heels outwards.
