Abstract
A single bolt, welded bicycle stem assembly for securing the handlebars to the front fork of a bicycle frame. The stem assembly includes a tubular barrel formed with a top end and side wall, and a sheet metal head section. The head section is formed with a cup-shaped top portion and a bottom portion which are bent in a U-shape so that the top portion overlies the bottom portion to form an annular sleeve therebetween adapted to receive and clamp the bicycle handlebars. The bottom portion is formed with spaced, parallel side sections having outwardly extending edges. The head section is adapted to engage the tubular barrel so that its top portion overlies the top end of the barrel and the outwardly extending edges of the bottom portion abut the side wall of the barrel. The head section is connected to a tubular barrel by vertical welds between the outwardly extending edges of the spaced side sections of the bottom portion of the head section and the side wall of the barrel.
