ABSTRACT:
A bicycle derailleur for attachment to a bicycle frame includes a base member apparatus having a first projection and a coupling member for coupling the base member apparatus to the bicycle frame. A chain guide is coupled to the base member apparatus for movement relative to the base member apparatus and for guiding a chain among a plurality of sprockets. The first projection is adapted to rotate relative to a second projection formed on a second member facing the first projection when the base member apparatus is mounted to the bicycle, and a shock absorber is adapted to be disposed between the first projection and the second projection for absorbing shocks between the first projection and the second projection.
