ABSTRACT:
A multi-functional control lever adapted for selectively operating on a front speed change device or a rear speed change device of a bicycle comprising a manually manipulable handle portion and a mounting portion rotatably mounted on a shaft. The lever has a housing for receiving a pin on the extremity of the cable and the cable is wound on one of two surfaces of the lever having different radii measured from the axis of rotation of the lever. The surfaces of different radii are brought into operative position by simple reversal of the lever on the shaft. The levers can be mounted at opposite sides of a common support block which supports the shaft and is attached to the frame of the bicycle.
