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).

[ We claim:] [1.] A clipless bicycle pedal system for releasably attaching a bicyclist's shoe to a bicycle, said clipless bicycle pedal system comprising:a pedal body rotatably mounted on an axle, said axle being removably attached to a crank arm of a bicycle, said pedal body having a center, a leading edge and a trailing edge, and having a first and a second surface; anda cleat comprising a cylindrical portion having a plurality of fractionally cylindrical slots of predetermined first arc length formed therein, and having mounting means for affixing said cleat to a bicycling shoe and a vertical axis coincident with the arc center of the cylindrical slots; anda plurality of engaging mechanisms disposed on either or both of said first and second surfaces, each of said engaging mechanisms comprising a tongue and an urging means, said tongue having a fractionally cylindrical portion of predetermined second arc length, said tongue cooperating with said urging means and being adapted to resile into and be removably seated in one of said slots in said cleat under the influence of said urging means; andwherein the tongue fractionally cylindrical portions combine and cooperate with said fractionally cylindrical slots to releasably capture said cleat on the pedal and allow said cleat to rotate about said vertical axis up to plus or minus a predetermined angle, thereby providing pedal float, and wherein said cleat will be released from the pedal when said cleat is rotated to an angle greater than said predetermined angle.
