ABSTRACT:
An archery compound bow having first and second opposed limbs. The bowstring rigging typically includes a power cam associated with the first limb, and a pair of idler wheels associated with the second limb. Drawing the bow by retracting the drawstring to rotate the power cam causes the idler wheels to rotate at different rates of angular displacement. The bowstring rigging can be arranged to rotate the idler wheels in either the same direction, or in different directions.
