An expendable bicycle headset structure (11, 211) is provided to aid in the mounting of a steerer tube (18a) of a front fork (18) to a head tube (12d) of a bicycle frame (12). The headset structure (11, 211) has a first tubular member (61, 261) and a second tubular member (63, 263) that are mounted on the steerer tube (18a). First and second tubular members (61, 261, 63, 263) have bores (76, 276, 86, 286) that are sized to receive the steerer tube (18a) therethrough. First and second mating adjustment structures (75, 275, 85, 285) are adjustably coupled together to change an effective overall axial length of the expandable bicycle headset structure (11, 211). Thus, the first and second mating adjustment structure (75, 275, 85, 285) apply an axial force to a headset (20) that rotatably mounts the steerer tube (18a) of the front fork (18) to the head tube (18a) of the bicycle frame (12) <IMAGE> |
