Abstract
In one aspect, the invention includes an archery bow having a first limb and a second limb, and a handle between the limbs. A rotating member includes at least two cams rotatably joined to the first limb with a first of the at least two cams having an eccentric profile to provide a first camming surface and a second of the at least two cams having an eccentric profile to provide a second camming surface. The eccentric profile of the first cam is substantially symmetrical relative to the eccentric profile of the second cam. A string extends between the rotating member and second limb.
