Grooves are formed in the circumferential edge of the block, with at least one groove each in the leading and trailing edges of the block. The cleat is a plate which is to be fixed to the sole of a rider's shoe and has a concave recess therein which corresponds to the convex surface of the pedal block. Within the recess is a spring-loaded tongue which is adapted to be removably seated in the grooves of the pedal block.
