ABSTRACT:
Torsional stress of a cyclist's leg is minimized by providing spaced limit surfaces on opposing parts of a cycle pedal and a shoe cleat that are designed for step-in, twist-out engagement. Floating adjusters, in the form of threaded rods, are rotated to select the effective width of spaces between the spaced limit surfaces. The full width of the space allows full floating rotation of the cleat relative to the pedal, whereas adjustment of the rods selects smaller floating rotating of the cleat relative to the pedal. The spaced limit surfaces and the rods are provided in LOOK and SAMPSON types of step-in, twist-out pedals.
