Abstract:
A multi-speed hub for cantilever mounting to a bicycle frame generally includes a planetary gear mechanism, a hub shaft, a hub shell, a spoke shell, a driver and a driven gear. The hub shell is cantilever-mounted to the bicycle frame and configured to enclose the planetary gear mechanism and the hub shaft. The spoke shell, driver and driven gear are rotatably supported by the hub shell. One end of the hub shaft is indirectly supported by the hub shell and the other end of the hub shaft is fixed to the bicycle frame.
