A compound archery bow of simplified construction includes a bowstring secured intermediate its ends to eccentrically pivoted cams mounted at the outer ends of the limbs secured to the opposite ends of a handle member. A control cable connects each cam pivot shaft, and therefore each limb, to a laterally projecting post on a lever mounted pivotally on the end of the handle member that secures the opposite limb. The end segments of the bowstring are trained around the cams and through the diametric center of each cam wherein the segments are secured. Each terminal end portion of the bowstring end segments is secured either to a winch located on the lever mounting the associated cam, or directly to said lever. The connection of the limbs to each other through the control cables and the bowstring end segments secured to the levers balance the flexure of the limbs relative to each other as well as the rotation of each cam as the bowstring is drawn back. Adjustment of the length of the bowstring terminal end portions effects adjustment of the tension and flexure of the limbs, pull weight of the bowstring and angular disposition of the cams.
