Abstract
A pulley assembly for a compound bow comprises a draw cable pulley, a power cable pulley attached to the draw cable pulley, and a cable deflector attached to the draw cable pulley and adjustable among multiple deflector arrangements. Deflection of the power cable by the cable deflector remains constant throughout drawing of the bow. Movement of the cable deflector alters deflection of the power cable to alter effective length of the power cable and relative synchronization (with the bow at brace) of the pulley assembly with a second pulley assembly. The adjustment can in some instances be performed without using a bow press and without derigging the bow.
