Bicycle disk wheel and process for the construction thereof

A process for the construction of a wheel for bicycles, especially sports and competition bicycles, of the type comprising a hub rotatable on a pin fixed to a bicycle fork, a rim carrying a tire and means connecting the hub and the rim, said process comprising:

• forming said connection means of two inclined flat sidewalls made of synthetic resin reinforced with radial fibers;
• firmly anchoring said sidewalls to the hub and to the rim;
• and tension stressing said sidewalls between the hub and the rim, said process further comprising:
• forming each of said sidewalls with a desired inclination by applying a plurality of triangular elements of textile fiber pre-impregnated with resin side by side and overlapping on a mold, so as to obtain a truncated cone with outwardly projecting edges;
• applying at the center of each of said sidewalls a counterflange for connection to a corresponding flange of the wheel hub;
• compressing said wheel rim until its radius has been reduced by a desirable degree;
• fitting said two sidewalls onto said compressed rim by enveloping said compressed rim with said outwardly projecting edges and fixing them thereto;
• polymerizing said resin by heating the same in an oven while maintaining said compression of said rim;
• removing said compression from said rim;
• and
• inserting the hub into said wheel by connecting said flanges to said counterflanges so as to draw said flanges and said counterflanges mutually apart.
