This is the one cleat to rule them all. Shimano Pedaling Dynamics, shortened to SPD, has long been the standard for clipless pedal systems. 

• Releases in lateral twist mode, with 4 degrees of float
• Stock replacement cleat for all Shimano SPD pedals
• Regularly replace cleats to maintain proper pedal function and foot stability
• Frequent riders should replace their cleats at least once per year
• Use with 2-bolt mountain bike, gravel, or fitness shoes
