A compound archery bow having two rigid bow arms pivotally hinged to opposite ends of a central handle section. Two flexible cables are connected between a single adjustable spring and the bow arms on opposite ends of the central handle section. The two cables properly coordinate the angular rotation of the opposing arms to provide a propelling force vector directly along the axis of the arrow shaft. These cables are attached to the bow arms such that the force needed to draw the bow string back is highest at about mid-draw and minimized at full draw.
