ABSTRACT:
A bicycle (10) with a frame (12) formed of composite material is disclosed. The frame of this bicycle includes a head section or module (34) that is attached to two body units (36, 38). The body units are formed by injection molding and include outer shells and inner ribs 200. Alternatively, the body units may be formed of a urethane core with a stiffened fiberglass, carbon fibers, or like nonmetallic skin. The head section and body units are formed with bores (78, 81, 83, 90) in which sleeves and cables are seated to accommodate the installation of the other components of the bicycle to the frame. The body is further formed with a set of rearwardly extending members that form the chain stays (22) of the bicycle. Dropouts (104) are seated in recesses formed in the chain stays. The bicycle includes a front derailleur/rear brake assembly (30) with a front derailleur (134) that can be both selectively moved up and down and selectively pivoted along a lateral axis of the bicycle. A one-piece, injection-molded frame and methods of construction are also disclosed.
