Abstract
A bicycle frame comprising a first tubular member having a first main portion and a first interface portion (e.g., a rounded taper), and a second tubular member having a second main portion and a second interface portion engaged with the first interface portion to create a joint. The joint includes a peripheral channel defined between the first interface portion and the second interface portion, and a weld is positioned in the peripheral channel. The second interface portion is defined at least partially by a substantially flat face wall. Preferably, the first tubular member includes an open end at the first interface portion, while the flat face wall at the second interface portion is substantially closed. In addition, it is preferred that the face wall lies in a plane that is substantially parallel to a longitudinal axis of the head tube (e.g., within ten degrees of the longitudinal axis).
