A method for producing a bicycle wheel rim is disclosed. The method
involves extruding a thin-walled, hollow body having the cross-sectional
shape of the rim and an integral external tab. The walls of the hollow
body are sufficiently thin that a length of the hollow body without the
external tab is subject to buckling when roll formed to produce a rim.
The tab is so positioned and sized that the hollow body with the integral
external tab is not subject to buckling when roll formed. A portion of
the extrusion is then rolled to a circular shape; the circular portion is
cut from the extrusion; the free ends are connected, and the external tab
is removed.
