Abstract
A stem assembly for securing the handlebars of a bicycle to the frame of the bicycle, which stem comprises a barrel and a head, the head being formed from a sheet metal stamping comprising a neck section and a handlebar clamping section. The neck section of the head is of generally annular cross-sectional configuration and is characterized by a longitudinal seam extending for the length of the neck. The seam of the neck section of the head is welded along the seam so as to impart to the stem resistance to torsional failure of the neck.
