Method for manufacturing a bicycle rim and bicycle rim

A method for producing a bicycle rim comprising a rim body with at least one cavity integrated within it, wherein the rim body extends in a rim plane over a circumference of 360° transverse to its rotational axis, and wherein the cavity forms a hollow chamber in the rim body,;

• the method comprising:
• wherein a plurality of component walls are formed, wherein the component walls comprise two lateral rim flanks, a radial inner rim base and a radial outer rim well, which delimit the hollow chamber;;
• wherein a support structure of the rim body is formed by at least one fibre structure;
• wherein for the production of the fibre structure a fibre bundle is attached to a carrier layer with thread elements and is passed back and forth on the carrier layer to form a basic fibre layer of the fibre structure;
• and
• wherein at least one fibre structure is draped in a tool mould, and wherein one filling unit is placed in the tool mould so that the filling unit keeps the volume free for the cavity and is surrounded by the component wall.
