A shifter designed to actuate a gear change device of a bicycle by pulling and releasing a control cable. The shifter includes a base plate mountable to the bicycle, a cable spool and cable-pull and cable-release lever assemblies. The cable spool is rotated in a cable-pull direction to wind the control cable thereon and in a cable-release direction to unwind the control cable therefrom. The cable-pull and cable-release lever assemblies are operatively connected to the cable spool to rotate the cable spool in the cable-pull and cable-release directions, respectively. The cable-pull lever assembly includes a cable-pull lever rotated about a first axis and at least two winding pawls received by and rotating with the cable-pull lever about the first axis to transmit rotational movement of the cable-pull lever to the cable spool.
