ABSTRACT:
A headset for bicycle having external forks. The headset allows the use of small standard sealed radial ball bearings, and allows for easy fork replacement by removing and replacing only two screws. Ball bearings with outer and inner races are inserted into bearing bores of the head tube of a bicycle frame. A pair of internally threaded bushings insert through the bearing inner races and are drawn together by a stud. Fasteners, such as screws, insert through mounting holes in spaced-apart mounting brackets of the external forks and engage the two bushings to secure the forks to the headset.
