ABSTRACT:
This invention comprises a pedal (18) with engaging mechanisms (41) fixed thereon, and a cleat (10) affixed to a bicyclist's shoe by a clamp (101), thereby allowing the neutral position of the float to be adjusted and controlled and indexed. The cleat (10) is cylindrical, with fractionally cylindrical slots (12) formed thereon. The engaging mechanisms comprise a concave, fractionally cylindrical tongue (20) corresponding to the slots (12) in the cleat (10). Tongue (20) is spring loaded, and cooperates with the slots (12) in the cleat (10) to releasably capture the cleat (10) on the pedal (18). The fractionally cylindrical shape of the tongue (20) and slots (12) allow a predetermined and adjustable amount of float of the cleat (10) and the rider's foot, while remaining securely captured on the pedal (18).
