The stem comprises a top plate, a bottom plate, a barrel and threaded nuts and bolts for securing the bottom plate to the underside of the top plate. The plates have opposed transverse arcuate grooves formed thereon for the reception of a handlebar therebetween. The top plate has a gusset punched upwardly from the underside to define a hole for the reception of the upper end of the barrel. The upper end of the barrel is welded to the top plate by a weld which extends between the side of the gusset, the barrel, and the top side of the top plate. Another weld surrounds the barrel and secures it to the underside of the top plate.
