A headset for a bicycle, comprising (a) the upwardly extending hollow cylindrical stem of the steering fork of the front wheels of a bicycle, (b) the downwardly extending cylindrical handlebar stem positioned within the fork stem telescopically, (c) a contractile clamping ring surrounding and connected by threads to the upper end of the fork stem and having at its upper part an un-threaded internal surface surrounding the adjacent part of the handlebar stem and a frusto-conical external surface, (d) a locknut loosely surrounding the handlebar stem and connected by threads to the clamping ring, and having a frusto-conical internal surface engaging the frusto-conical external surface of the clamping ring whereby screw threaded movement of the nut toward the ring contracts the ring to cause engagement of the un-threaded internal surface of the clamping ring with the handlebar stem, and (e) means for releasably connecting the clamping ring to the fork stem to prevent loosening of the connection between these parts.
