A stop for handlebars of two-wheeled vehicles is integrated into the control head bearing of the vehicle. It is formed by a first component installed in the control head bearing with a circular arc-shaped groove that is arranged coaxially to the rotational axis of the control head bearing and a stop element protruding into this groove. The stop element is arranged on a second component that can be moved relative to the first part. The stop at the lower control head bearing is arranged within the head tube. The circular arc-shaped groove is arranged in the base and open towards the lower bearing shell. The lower bearing shell comprises an open recess extending over its height to the lower rolling bearing, which receives a stop element. The stop element has a radial lug protruding into the circular groove of the base.

A transmission element for arrangement between a handlebar stem and an upper headset includes a cover ring which, in the mounted state, covers an upper headset. An intermediate ring surrounding a head tube is arranged above the cover ring. To compensate for clearance changes of the headsets, a pretensioning element is arranged between the cover ring and the intermediate ring.
