A bicycle disc or spider wheel including: a hub; a rim having a radially outer tire-coupling region, a first sidewall, a second sidewall; an axis of rotation; and a median plane. A pair of pretensioned disc or spider wheel-type structural elements are integral with the hub and with the rim. The first sidewall extends on a first side of the wheel, with respect to the median plane, on which a component of a motion transmission system or, when there is none, a disc of a disc brake is provided at the hub, and the second sidewall extends on the opposite side, with respect to the median plane. The first sidewall of the rim has a minimum distance from the median plane that is smaller than that of the second sidewall of the rim.

A bicycle wheel contains a rim, multiple spokes, and multiple abutting faces. The rim includes multiple through orifices, a hub, and multiple threaded orifices. Two intersected spokes are connected with two adjacent through orifices and two threaded orifices corresponding to the two adjacent through orifices respectively. Each spokes includes a first screwing section and a second screwing section. The second screwing section is screwed with each of multiple nuts and each of multiple second screw bushings. The multiple abutting faces are connected with the multiple spokes respectively. Each spoke includes an axial line defined along a center thereof. An angle is defined between each abutting face of the rim and the axial line of each spoke and is 90 degrees. Two connection sections are formed on two ends of each abutting face.

The present disclosure relates to a rim for a wheel. In one aspect, there is provided a rim for a wheel. The wheel comprising a rim, spokes, and hub. The rim depth varies wherein the section approximately half way between spoke connection points to the rim is of the greatest depth. Further, the section of rim located between the spoke connection point to the rim and the centre-point of the rim between spokes is of the shallowest depth. The spokes being of the type to provide support under forces of compression and tension. In a further aspect, there is provided a wheel comprising the rim.

A lightweight wheel with high strength flexible spokes of the present invention, includes 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 rim comprising a circumferential outer portion adapted to receive a tire and a spoke bed. The spoke bed may comprise a pattern of spoke attachment segments at varying tilt angles and spaced by intermediate segments. Each spoke attachment segment may comprise an inner surface, an outer surface and a spoke opening extending from the inner surface to the outer surface. The spoke opening may be sized to accommodate a spoke nipple. The spoke opening may have a central axis angled at a complex angle that is a combination of a respective camber angle and a respective crossing angle. The complex angle may be selected to achieve a respective spoke angle. The outer surface of the spoke attachment segment adjacent to the spoke opening may extend perpendicular to the central axis of the spoke opening.

A rim for a vehicle wheel, including a spoke bed wall having: a radially outboard surface; a radially inboard surface; and a spoke hole extending between the outboard surface and inboard surface and configured to receive a spoke of the vehicle wheel; an insert having: a radially outward surface; a radially inward surface; and an opening extending between the outward and inward surfaces and configured to receive the spoke; an adhesive to provide an adhesive joinder between the insert and the outboard surface. The insert opening has a radially outboard first entrance with a first perimeter edge. The insert opening laterally overlaps the spoke hole. At least one of the first perimeter edge, the outward surface, and the insert opening is configured to provide a bearing surface to brace the spoke.

A spoke tension adjustment tool has a longitudinally elongated body with a central longitudinal cavity configured to house an end portion of a spoke. The housing has a longitudinal slit that allows the end portion of the spoke to enter the longitudinal cavity. The longitudinally elongated body has a grip portion and a shaped end portion configured to couple with a stem of a spoke attachment element. The shaped end portion is smaller than the grip portion and smaller than the diameter of a rim spoke attachment hole in which the stem is inserted.

An abutment interface located between a spoke attachment nipple and a bridge of a rim to properly align the tensioned spoke with the rim. The abutment interface includes a first washer with a radially inner face that abuts the bridge and a radially outer face that abuts with a radially inner face of a second washer that has a radially outer face that abuts an enlarged head on the nipple. The faces of two washers are complimentarily shaped and adjust with respect to each other and the nipple head. An initial adjustment takes place when the fixing the spoke to the rim and the washers prevent any further adjustment when fixing the spoke to the rim.

The present invention relates to a method of assembling a rim, in particular a bicycle rim of composite material. The invention further relates to a rim obtainable by such a method.

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.
