    a cable pulley component with a non-circular peripheral cable take-up groove; and

    a dynamic synchronizing component;

    a bowstring with opposite ends connected to said first and second pulley assemblies such that, at rest condition of the bow, the peripheral string grooves are substantially occupied by wrapped bowstring;

    a first cable segment, extending from the entry of the peripheral cable take-up groove of said first pulley assembly to the dynamic synchronizing component of said second pulley assembly; and

    a second cable segment, extending from the entry of the peripheral cable take-up groove of said second pulley assembly to the dynamic synchronizing component of said first pulley assembly;
