ABSTRACT:
A quick-release bicycle derailleur includes a base member, a movable member supporting a chain guide, and a linkage mechanism coupling the base member to the movable member so that the movable member moves relative to the base member. A draw bar extends from the base member and has a cam follower at the base member. A rotary cam is supported by the base member and contacts the cam follower so that rotation of the rotary cam pulls the drawbar into the base member. A nut may be fitted to the other end of the draw bar so that the base member and the nut securely fix the derailleur to a pair of fork ends on the bicycle frame.
