Abstract
In some embodiments, an archery bow comprises a frame supporting a first limb and a second limb. A first rotatable member is supported by the first limb and arranged to rotate about a first rotation axis. The first rotatable member comprises a cam track. A second rotatable member is supported by the second limb and arranged to rotate about a second rotation axis. The second rotatable member comprises a synchronizer track. A bowstring extends between the first rotatable member and the second rotatable member. A power cable is arranged to be taken up on the cam track and fed out from the synchronizer track as the bow is drawn. The synchronizer track is circular and a centerpoint of the synchronizer is offset from the second rotation axis.
