ABSTRACT:
A high performance cycle seat which provides support of the buttock muscles of a cyclist includes a frame, a shell supported on the frame, and wherein the frame and shell include a raised anatomical rear portion which defines a chock for longitudinally supporting the buttocks of the cyclist when the cyclist is hunched over a cycling position. The rear portion includes a forward-facing median wedge, which has a generally epsilon shape in horizontal cross-section. The latter also includes a pair of sloping curved side portions. The wedge prevents lateral displacement of the buttocks, and its width increases in a direction towards its upper rear edge. A longitudinal median zone is arranged forward of the raised rear portion and is aligned with the wedge. A pair of symmetrical support concavities extend downwardly and forwardly from the curved side portions along opposite sides of the median zone, respectively; the zone and the concavities merge towards a forward portion of the seat, so that the seat is configured to maximize the efficiency of the pedalling by the cyclist, by providing optimum support for the buttock muscles.
