A multi-speed bicycle hub and an operating mechanism thereof

摘要

A multi-speed bicycle hub is combined with an operating mechanism. The operating mechanism is fastened to a hub shaft. In the operating mechanism there is provided a linearly movable operating slide. This operating slide is provided with control tracks. The control tracks act on pivot levers. The pivot levers act on a control rod and a surrounding control tube provided within a hub shaft bore. The control rod and the control tube are in connection with a gear box within the hub sleeve. The control rod and the control tube are secured against being lost, when the hub is not yet combined with the operating mechanism.
