A method of manufacturing a lightweight wheel with high strength flexible spokes of the present invention, includes providing a rim and hub, and a plurality of lightweight, flexible and resilient spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The wheel includes a nipple within the rim that receives the high strength spoke and allows for flexibility in adapting the spoke to wheels having differing shapes and sizes.

A bicycle component comprises a first structural member made of a conducting material, an electrical insulation layer provided to the first structural member, and a second structural member configured to be attached to the electrical insulation layer by adhesive.

The present invention provides a single-point reinforcing structure for spoke of bicycle rim which includes a left side wall and a right side wall continuously extending along a circumferential direction of the bicycle rim. The left side wall and right side wall are formed at the left side and the right side of the bicycle rim respectively and are symmetrical to each other. A surface of the left side wall and a surface of the right side wall opposite to each other are connected through a connecting wall. The upper ends of the left side wall and the right side wall extend upward toward a direction close to a symmetry axis and are connected. The left side wall, the right side wall, and the connecting wall are surrounded to form an upper cavity of the bicycle rim. A plurality of connecting holes are arranged on the upper cavity.

A composite rim is used in spoked wheels, such as bicycle wheels. The composite rims has molded-in spoke holes. The composite rim is manufactured using a unique fabricating technique. The construction of the composite rim dramatically improves the bearing and loading strength of the composite rim over prior composite rims, which drill the spoke holes therein after fabrication of the rim hoop.

A spoked bicycle wheel having a rim at least partially comprised of a composite material. The rim has at least one spoke attachment chamber with a plurality of spoke attachment holes. The wheel has a plurality of spokes coupled with the rim and a spoke attachment element partially inserted in a respective spoke attachment hole. The wheel includes a holding element that prevents the movement of said spoke attachment element along a radially outer direction. The spoke attachment element has a holding surface configured for abutment against the holding element.

An insert for the rim of a spoked bicycle wheel that has a spoke hole. The insert has a portion configured to abut against a spoke attachment element with an enlarged head and a holding element that prevents movement of the spoke attachment along said longitudinal axis of the spoke hole.

A bicycle wheel rim made at least partially of a stratified composite material comprising structural fibers incorporated in a polymeric matrix. At least one opening, which passes through at least one first layer of composite material, is provided and at least one spoke attachment hole, which passes through at least one second layer of composite material, is also provided. The spoke attachment hole is completely contained within the opening in the first layer. A related manufacturing process is also described.

A wheel component, method, and tool device for a bicycle, including a plurality of integrally interconnected component parts, which form a spoked rim, wherein the rim and spokes are manufactured of a fibrous composite material by an injection molding process with fluid injection, wherein the liquefied fibrous composite material is injected into a cavity of a tool device, and a fluid is injected into the partially liquid fibrous composite material within the cavity to form at least one hollow space within the component part. A further component part forming a spoke, is manufactured by an injection molding process, wherein a mold core device for forming a hollow space within the spoke is disposed within a further cavity of the tool device. The fibrous composite material is injected into the further cavity. The mold core device is retracted from the fibrous composite material to form a cavity in the spoke.

A wheel with flexible spokes, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength.

A bicycle wheel comprising an annular rim having an inner circumferential portion, an outer circumferential portion and a pair of side portions that extend between the inner circumferential portion and the outer circumferential portion. Each side portion comprises a primary surface and a plurality of pockets that are recessed below the primary surface.
