Abstract

An archery bow system incorporating a bow riser and dual limbs supporting cams or a cam and wheel mounted for rotation about respective axles. The dual limbs are independently adjustable to correct for cam lean and are individually supported in pockets that incorporate variable limb angle attachments to the bow riser. The limbs extend from the riser to flex, when at full draw, to positions that cause the respective axles to initially travel rearward toward the archer upon release of the bowstring. The limbs are adjustably attached to the riser to permit the limb angle with respect to the riser to be changed.
