ABSTRACT:
A handlebar assembly and method of making same includes cutting a straight handlebar tube to a desired length, forming a reinforcing member or slug to fit within the tube including drilling and tapping radial bores and forming a longitudinal groove in the slug for the passage of control wires etc. Somewhat larger diameter bores are formed near the center of the handlebar tube in registry with the bores in the slug. The slug is then fixed in the tube in the desired position after which the tube is bent to the desired configuration and handgrip sections are formed. The handlebar is then finished as by chrome plating. A mount is formed having bores spaced like those of the slug and a longitudinal groove to support the center section of the handlebar. The mount is then finished as desired. Threaded fastening members are then passed through the bores in the mount and the handlebar and are screwed into the threaded bores in the slug to secure the assembly together. The larger diameter bores in the handlebar tube permit angular adjustment of the handlebars. The slug may also be a tubular member or a semi-cylindrical member which accommodates the wires without requiring a longitudinal groove.
