A method of manufacturing a fibrous composite bicycle rim, employs a tool device having a plurality of tool components including two molding devices and one circular device. The two molding devices each have one rim flank contact surface. The circular device includes a rim well contact surface. Tool components are provided, and a first varnish coat is applied to a rim contact surface and is dried. A first fiber layer of the fibrous composite material is applied to the flank contact surface of the molding devices, forming the outer fiber layers of the pertaining rim flanks. At least one first fiber layer of the fibrous composite material is applied to the circular device which forms the rim well. The tool components of are interconnected, and the tool device is closed, is heated up, and the smooth varnish coat firmly bonds with the hardening fibrous composite material.

Rim, and method of manufacturing a rim

A facility and its use and method of examining the production quality of bicycle components with a control device, a heat source and a camera. The heat source applies heat on the bicycle component during a measuring process. The camera captures a spatially resolved thermal image of the bicycle component. The thermal image is evaluated to determine the production quality of the bicycle component. A deflecting device deflects heat radiation, to capture different sides of the bicycle component.
