A bicycle frame comprising a first tubular member having a first interface portion, and a second tubular member having a second interface portion engaged with the first interface portion to create a joint. The joint includes a peripheral channel having a depth that is greater than a wall thickness of the first tubular member, and a weld is positioned in the peripheral channel. To enhance the transition from the first main portion to the second main portion, the second tubular member can include a fillet surface between the second main portion and the second interface portion. The fillet surface is contoured to provide a smooth transition between the top tube and the head tube. An outer surface of the first interface portion can be offset from an outer surface of the first main portion to thereby create a shoulder.
