ABSTRACT:
An eccentric for mounting at the distal end of a limb of a compound archery bow includes a step-down take-up ramp which combines the features of the side-by-side and step-down eccentrics of known eccentrics while maintaining vane clearance and avoiding development of twist on the limb. The eccentric is also provided with a cable clamp device permitting adjustment of the draw of the bow and a pivot insert which permits adjustable pivot locations for the eccentric.
