Abstract

A method for manufacturing a double-layered bicycle spoke by forging comprises: drawing and cutting a while bundle of metal wires to form a single-layered spoke with a desired length; forging the intermediate section of the single-layered spoke to a smaller diameter; forming the head part of the spoke and bending the head for 90 degrees, followed by threading, thereby forming a double-layered bicycle spoke. This invention provides the following advantages: no damaging the axial fibers of the metal material, no affecting the strength of the spoke, increased strength after forging, saving material used, producing a product with a smooth surface and a attractive outlook.
