A rim assembly for a bicycle wheel is disclosed. The rim assembly comprises: a rim configured to receive a rim component in an external surface thereof, and; a rim component located in the external surface of the rim, wherein the rim component forms part of the external surface of the rim, and wherein; the rim component has a lower density than the rim. A rim, insertable rim component and methods of manufacturing such a rim assembly are also disclosed.

A vehicle wheel, including a rim, a hub, and a plurality of spokes, a first anchor to connect one of the spokes to one of the rim and hub at a connection interface. One of the spokes is pre-tensioned by a pre-tensioning means. The first anchor may be manipulated between: (i) a released orientation where the connection interface is longitudinally released from the spoke to permit independent longitudinal displacement therebetween; and (ii) an engaged orientation where the connection interface is longitudinally connected to said spoke to limit independent longitudinal displacement between the two and to maintain the pre-tension of said spoke. The pre-tensioning means is discreet from the first anchor.

Bicycle hub includes a shell rotatably supported relative to a hub axle, a rotor rotatably supported by two rotor bearings, and a freewheel device having two interacting freewheel components: a hub-side freewheel component and a rotor-side freewheel component. The freewheel components each include axial engagement elements and are axially movable relative to one another between a freewheel position and an engaging, driving torque position. The hub-side freewheel component includes a threaded axial body section and is screwed into the hub shell. The hub-side freewheel component has an axial, annular surface on which the axial engagement elements are configured. The rolling members of a hub bearing show a defined accommodation inside the hub-side freewheel component to support the shell relative to the hub axle. The hub-side freewheel component includes a tool contour which couples to an adapted tool for releasing the screw connection of the hub-side freewheel component with the shell.

A wheel rim for a vehicle including a first rim portion including a first wheel flange, a second rim portion threadedly connected to the first rim portion, and a second wheel flange held on the first rim portion.

A wheel assembly to be coupled to a hub of a vehicle may include an inner rim to be coupled to the hub of the vehicle and an outer rim surrounding the hub. The wheel assembly may also include gas springs operatively coupled between the inner rim and the outer rim to provide a gas suspension for relative movement between the inner rim and the outer rim. The wheel assembly may also include a disk coupled to the inner rim. The wheel assembly may also include inboard lateral stops carried by an inboard interior surface of the outer rim, and outboard lateral stops carried by an outboard interior surface of the outer rim so that the inboard lateral stops and the outboard lateral stops cooperate to limit relative lateral movement of the disk and the outer rim.

A wheel assembly to be coupled to a hub of a vehicle may include an inner rim to be coupled to the hub of the vehicle and an outer rim surrounding the hub. The wheel assembly may also include gas springs operatively coupled between the inner rim and the outer rim to provide a gas suspension for relative movement between the inner rim and the outer rim. The wheel assembly may also include an outer ring coupled to the outer rim and defining a closeable gap with adjacent interior portions of the inner rim to define a mechanical stop to limit relative movement of the inner rim and outer rim.

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 manufacturing method for a wheel disc, includes forming a flange portion, wherein the flange portion is formed such that an inner mold and an outer mold having a cylindrical inner surface with a first inside radius larger than the first outside radius and placed above the inner mold coaxially to the inner mold are brought close relative to each other in an axial direction by one stroke so that the outer edge of the disc material is bent downward, and the cylindrical inner surface of the outer mold is provided with recessed portions hollowed outwardly in a wheel radial direction, the recessed portions being formed in ranges corresponding to the window portions in the wheel circumferential direction and in a range from a middle position to a bottom end in the wheel axial direction.

A wheel assembly to be coupled to a hub of a vehicle may include an inner rim to be coupled to the hub of the vehicle and an outer rim surrounding the hub. The wheel assembly may also include gas springs operatively coupled between the inner rim and the outer rim to provide a gas suspension for relative movement between the inner rim and the outer rim. The wheel assembly may also include an outer ring coupled to the outer rim and an inner ring coupled to the inner rim and defining a closeable gap with adjacent portions of the outer ring to define a mechanical stop to limit relative movement of the inner rim and outer rim.

A wheel with high strength flexible spokes of the present invention, 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. 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.
