Claims8
A method for manufacturing a rim, in particular for bicycles, comprising:
- manufacturing a rim body having a hollow space defined by opposing sidewalls, comprising a continuous, radially outer hollow-spaced wall and a radially inner hollow-space wall;
- providing the radially outer hollow-space wall with a diameter matched to a diameter of a tube tire, wherein the outer hollow-space wall serves as a rim base for the tube tire;
- and
- providing the radially inner hollow-space wall with a diameter matched to a diameter of a wire tire, wherein the outer hollow-space wall is removed such that the inner hollow-space wall serves as a rim support for the wire tire and the opposing sidewalls remain to form rim flanges adapted for retaining the wire tire.
