ABSTRACT:
Eccentrics for a compound bow are provided with a string sheave and a cable sheave, at least one of which is provided in segments adjustable to alter the course of the cam ratio effected through the eccentric. Ideally, the portion of the cable sheave corresponding with post peak force-draw positions is adjustable to alter the separation of the cable from the pivot axis of the eccentric at the valley position of draw.
