ABSTRACT:
A combination bicycle fork and steering tube assembly is formed with a pair of downwardly directed, mutually converging end closure tabs that are bent over into abutment and welded together to define peripherally enclosed fork openings at the ends of the steerer tube. The upper ends of the hollow fork legs are configured to follow the surface contours of the lower end of the steerer tube and are welded to the end closure tabs about the circumferences of the enclosed fork openings at the lower end of the steering tube. The front wheel axle dropouts are formed directly in the lower ends of the fork legs, which include internal dropout support inserts. The dropout support inserts are sandwiched in between a pair of flat, mutually parallel dropout tabs defined directly in the lower ends of the fork legs.
