Abstract

A compound archery bow includes a bow handle having projecting limbs, and first and second pulleys mounted on the limbs for rotation around respective axes. A bowstring cable extends from a bowstring anchor through a bowstring let-out groove on the first pulley and then toward the second pulley. A first power cable extends from a first power cable anchor toward the second pulley, and a second power cable extends from the second pulley through a power cable take-up arrangement on the first pulley to a second power cable anchor on the first pulley. A set of at least first and second bowstring cable draw length adjustment modules is provided for alternate mounting on the first pulley to adjust draw length of the bowstring cable away from the handle. Each of the modules includes a first portion for mounting adjacent to the first axis, an intermediate portion that includes a power cable take-up groove that constitutes at least part of the power cable take-up arrangement on the first pulley, and a heel portion for mounting spaced from the first axis and adjacent to the power cable anchor such that the power cable take-up groove extends around the heel to a position adjacent to the power cable anchor. The heel is larger on one of the modules than on the other.
