Abstract

The bicycle change-speed gear has a central shifting device for the chain, and a single control lever. The latter has a spindle (1), widened at one end to form a washer (2) limiting the amount of movement and with a notch (3) extending for a quarter of its periphery. The washer is fixed to the frame and has guides for the operating cables, these cables being supported by two discs fitted on the spindle and separated from each other by thrust washers on opposite sides of the thrust sleeve. A flexible rounded-section plastics washer fits on the sleeve and supports the control lever, so that this can both turn freely and tilt sideways.
