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.

The present invention discloses an opening-prefabricated carbon fiber spoke and a method for preparing thereof. The opening-prefabricated carbon fiber spoke includes: a spoke body made of carbon fiber, a nipple, and a nipple head. Both ends of the spoke body are a first fixed connector and a second fixed connector. The nipple is sleeved on the second fixed connector of the spoke body. A forked part of the second fixed connector is provided with a wedge pin. According to the present invention, a slope is formed at both ends of the spoke body, and the two ends are increasingly tight under an action of a pulling force, which greatly improves a tensile strength.

To provide a bicycle hub unit and a bicycle wheel assembly that allow a wheel unit to be appropriately coupled to a hub body, a bicycle hub unit is coupled to a rotary body to which a brake is applied by a brake device. The bicycle hub unit includes a hub body that rotates around a hub axle and a rotary body coupling portion that couples the rotary body to the hub body. The hub body includes a first joint portion and a second joint portion. The first joint portion includes an external thread coupled to an internal thread of the wheel unit. The second joint portion is coupled to a restriction member that restricts relative rotation of the first joint portion and the wheel unit.

A wheel for a two wheeled vehicle including a flange and a plurality of spokes, the spokes connecting the rim to the flange, wherein brake force spokes of the plurality of spokes are stronger than drive force spokes of the plurality of spokes. In one alternative, the flange has an inner and an outer area.

A rim of a bicycle wheel with a wall that, viewed in a radial section, extends along a closed line enclosing at least one annular cavity that is concentric with the rim. Partitioning the rim in three slices of equal size along the axis of rotation yields wall projections that have axially central portions that extend radially outwards to a greater extent than axially outer portions.

A rim for a bicycle wheel includes a radially inner portion disposed along an inner circumference of the rim, a first sidewall, and a second sidewall spaced apart form the first sidewall. The first sidewall and the second sidewall extend radially outward from the radially inner portion. The radially inner portion includes a stack of strips of material. The stack of strips includes a plurality of strips and a hole through the plurality of strips. The plurality of strips are nonparallel to each other. The plurality of strips are positioned about the hole through the plurality of strips.

A bicycle wheel assembly may include a rim, a hub assembly, a plurality of spokes and a damper assembly. The damper assembly includes a damping element configured to apply a damping force against at least one spoke of the plurality of spokes. The damping force may be applied in an axial direction of the bicycle wheel and/or to a segment of the at least one spoke near the hub assembly.
