摘要

The invention relates to an assembly comprising a bicycle fork (1) and a headset (J) on a steering column (2) of a bicycle frame. According to the invention, the fork is solidly connected to a pivot (3) which extends (3a) beyond the end of the steering column, opposite that comprising the fork, such that a handlebar stem can be fixed thereto using the external screw thread of the pivot. The aforementioned headset (J) comprises a lower bearing (7) and an upper bearing (8) and an adjustment means (M) is provided for the axial clamping of said headset. Moreover, in the area at the end of the steering column opposite that comprising the fork, the outer surface of the pivot (3) contains a zone (B) which is equipped with first connecting means (13), while the above-mentioned pivot extension (3a), which is disposed at the end opposite that comprising the fork (1), has no such connecting means. The invention further comprises a bushing (15) which is equipped with second connecting means (16), complementary to those of the pivot, and which is used to adjust the axial clamping of the headset.
