ABSTRACT:
A bicycle (10) with a frame (12) formed out of composite material is disclosed. The frame of this bicycle includes a head unit or module (34) that is attached to two body units (36, 38). The head unit and body unit are formed out of a urethane core and can be formed of stiffened fiberglass, carbon fibers, or like nonmetallic material. The head unit 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 from 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. By selecting an appropriately sized head unit, the frame of the bicycle can built to a specific size. Components of specific dimension can then be attached to the frame to facilitate the construction of a bicycle of this invention so that it is built for a cyclist of a specific size.
