Method for increasing the structural strength of spokes of a bicycle or motorcycle.

摘要

A method for manufacturing a radius for a bicycle or motorcycle in which structural strength of parts of the radius increases during manufacture, the method comprising and characterized by starting a wire section of constant cross section and using a mechanical process to compress the wire a plurality of times and by the compressions: reducing a cross-sectional view of a main body portion radio (1) of the wire; increasing a cross section of a bending section (2) and a neck section (3) of wire; increasing structural strength of the bending section (2); and hardening the neck section (3) and the bending section (2) to increase the strength thereof; and subsequently bending the wire at the bending section (2) to leave the neck section bent away from the main body.
