ABSTRACT:
A bicycle frame includes a top support tube extending rearwardly to a welded connection with a rear fork structure. The rear fork structure has another welded connection with an upstanding seat tube. Aligned holes are formed in the top support tube so that the seat tube can extend downwardly through the openings; the seat tube is welded to the top support tube at the aligned openings. The various tubes are arranged and proportioned to provide a welded triangular reinforcement designed to diffuse and absorb road impact forces generated at the rear wheel of the bicycle.
