SPD's were designed for users wanting a clipless pedal system but the ability to walk comfortable if the need arose. These cleats fit tidily on the bottom of your shoe making this possible!
The Shimano SM-SH51 Cleat has been designed with mountain bikers in mind. This strong and durable cleat keeps for fopot in place when it needs to be and can take a hammering! The SM-SH51 cleat is released in one direction by moving your heel outwards and is easy to clip back in place when required. Unlike the SM-SH56 this cleat can only be released in one direction rather than any direction.
