Abstract
A bicycle handlebar stem for attaching a handlebar to the steering tube on a bicycle includes a continuous wall section which extends continuously and completely around the steering tube from one side to the other of a tubular central portion of the stem without any gaps or spaces therebetween. A slot in the center of the tubular central portion of the stem provides a means for reducing the diameter of the central opening formed by the continuous wall section for attaching and tightening the stem onto the end of the steering fork. An arcuate-shaped cover member on the opposite end of the stem, the cover member and stem and having cooperating semi-cylindrical clamping surfaces, provides a means for attaching and tightening the handlebar onto the stem. The cover member is attached to the stem by virtue of a mechanical hinge and a single fastener.
