ABSTRACT:
A pulley adapted to be mounted at each end of a bow and so constructed as to permit adjustments in the eccentric axis of rotation relative to a bow. Each pulley at the end of a bow includes a pair of annular grooves positioned in spaced relation around the periphery of the pulley. A first and second set of slots extend radially through the rim portion of each pulley and into the first and second annular grooves respectively. The sets of slots are diametrically opposed on the rim. The cable is reeved about each pulley and positioned in a selected pair of slots so that a preselected amount of cable is positioned on the pulleys corresponding to a preselected draw length and/or draw weight of the bow.
