A stem includes a stem body, one of the extremities of which includes element for attaching a handlebar, the opposite extremity including two parallel arms connected to a pivot tube by an articulation associated with clamping element which immobilize the stem in a chosen position. The clamping element includes a pair of frustoconical bodies connected to the extremities of the arms. The frustoconical bodies are received in housings of complementary shape. The frustoconical bodies are connected by a connecting element capable of moving them closer to one another in order to clamp them in the respective housing, and of loosening them by moving them further apart one from the other so as to allow the continuous adjustment of the inclination of the handlebar. The cone angle of the frustoconical bodies possesses a sufficiently low value to permit them to be pinched inside their housings.
