ABSTRACT:
A metal drop-out is attached to a receiving tube of a bicycle frame. The drop-out includes a slotted axle-retaining section and a mounting section which is of one-piece integral construction with the axle-retaining section. The mounting section is bent relative to the axle-retaining section along a transverse band region by an angle by about 10 to 90 degrees. An end edge of the mounting section is machined to a generally cylindrical configuration defining a first longitudinal axis. The machined end edge of the mounting section is inserted into an end of a receiving tube and is welded thereto.
