ABSTRACT:
A bicycle derailler which provides for an actuating mechanism which prevents stretching and breaking of the actuating cable by allowing an actuating link to move when the cable is tightened at times when the wheels of the bicycle are not moving. Under these conditions, when the actuating link is moved by the cable it spring biases the derailler mechanism such that when the bicycle starts to move the spring bias causes shifting of the derailler.
