Abstract
A compound archery bow has a riser with upper and lower power or spring limbs, and a synchronizing pulley system for ensuring equal flexing of the limbs. There are bowstring cam members rotationally supported at the outboard ends of the power limbs. An inboard power cam is mounted on a pylon on the riser, and an outer power cam is coaxially mounted with the bowstring cam member. Cam cables extend over the inboard and outboard power cams. The bowstring cam members are configured so as to increase in effective radius as the bow returns from a full draw position to brace height. The power cams can be configured as a quad cam system.
