Abstract: The handlebar for a bicycle or similar vehicle is clamped by a pair of pillow blocks which are bolted to a first plate which in turn is attached to the bicycle stem. The first plate has a portion stamped outwardly to form a second plate connected to the first plate and angularly disposed with respect to it. A rim is also pressed out of the plane of the first plate along the edge of the opening formed by stamping out the second plate, and an upper portion of the bicycle stem is received in the opening in the first plate and permanently attached to it by means of a fillet weld around the opening at the lower surface of the first plate. The undersurface of the second plate bears against the upper end of the stem and is bolted to it by a bolt that extends through the second plate and the stem.
