A method of manufacturing a spoke, including: reshaping a wire material to obtain a spoke blank by a forging device; wherein the spoke blank includes pre-stages of the central section and the end portions and the transition sections; and wherein the pre-stages of the central section and the end portions are forged cylindrically; the pre-stages of the transition sections are forged conically, so that they show a diameter decreasing in the direction of the central section; wherein the pre-stages of the transition sections are each manufactured in a length which differs by a maximum of one fourth from the pertaining length of the transition section; reshaping the spoke blank by a shaping tool, which reproduces a negative shape of the spoke body, so that the spoke body is generated; wherein at least the transition sections and the central section are each provided with a cross-sectional geometry different from their pre-stages.
A method of manufacturing a spoke for a wheel of an at least partially muscle-powered bicycle, having a spoke body, wherein the spoke body in an installed position in a wheel, comprises a hub-side, first end and a rim-side, second end, and wherein the spoke body comprises at least one central section extending between the ends, wherein one end portion is attributed to each of the ends, and wherein one transition section each is disposed between the central section and the end portions,
