Cam synchronization device for archery bow

Abstract

A timing adjustment assembly for a compound archery bow is provided. The timing adjustment assembly is coupled with a pulley assembly and power cable of the archery bow. The timing adjustment assembly includes an adjustable component and a stationary component. The stationary component is attached to either the pulley assembly, the power cable, or the riser of the archery bow. The adjustable component is configured to move in a linear direction between multiple positional arrangements relative to the stationary component. The movement of the adjustable component changes the effective length of the power cable by moving the termination anchor point of the power cable or deflecting the power cable. The timing adjustment assembly adjusts the effective length of the power cable and relative synchronization of the pulley assembly with the archery bow in a brace position.
