The method for the manufacture of a spoke for spoked wheels including a step of forming a head of the spoke at a longitudinal end of the shank thereof by equipment for the plastic deformation of the end of the shank, wherein the plastic deformation is obtained by maintaining the shank in relative rotation to the equipment.

The invention discloses an articulated nipple (1) for the fixation of a bicycle spoke (R) comprising an elongated body (2) and a washer (3). The body (2) comprises a radial protrusion (22) that protrudes radially therefrom, and the washer (3) comprises a radially inner face (31) conforming a radial cavity. Thus, the protrusion (22) is housed inside the radial cavity to conform an articulated connection between the washer (3) and the body (2). This articulated connection allows for the body (2) to rotate an angle () with respect to the washer (3) around an axis that is perpendicular to the longitudinal axis (ELA) of the washer (3).

A wheel component for a wheel of an at least partially muscle-powered two-wheeled vehicle, including a rim provided to be connected with a hub by means of spokes, the rim including a rim base with a plurality of spoke socket sections having one spoke hole each, to which the spokes can be attached by means of spoke nipples. The wheel component includes at least one washer for placement between a spoke socket section and a spoke nipple. The washer includes a through hole extending between a top face and a bottom face. The rim base includes two opposite rim flanks extending obliquely relative to one another. In its bottom face, the washer shows a canted support flank at least in sections. The washer can be supported on the rim flanks by means of its support flank such that only the support flank bears against, and contacts, the rim.

The invention discloses an internal converter nipple (1) for being mounted in a rim for external nipples. The nipple (1) comprises an elongated body (2) having a threaded internal orifice (21) configured for the connection of an end of a bicycle spoke (R) and a head (3) protruding radially from an end of said body (2). The nipple (1) further comprises an extension (4) at a side of the head (3) opposite to that where the body (2) is, said extension (4) comprising an internal orifice (41) configured for the passage on the end of the spoke (R). The external diameter (D) and the length (L) of the extension (4) are configured to fit into a hole (A.sub.E) of the rim (LL.sub.E) for external nipples (C.sub.E).

Spoke nipple for an at least partly muscle powered bicycle wheel, the spoke nipple being configured to connect a spoke to a rim of said wheel, wherein the spoke nipple comprises a spoke nipple head including an at least partly enlarged head portion configured to retain the spoke nipple in the rim.

A wheel component for bicycles with a straight spoke, with a center portion and two end portions, to detachably connect a hub with a rim. The spoke is supported on a hub and a rim by the end portions. The spoke is manufactured from a fibrous composite material and includes a matrix material and embedded reinforcing elements. The spoke is formed without loops and eyelets. The end portions are integral with the center portion, forming an end of the spoke each. At least one of the two end portions includes a threaded portion. At least some of the reinforcing elements are configured as long fibers extending through the entire center portion and over at least a substantial part of the two end portions each. At least one end portion includes a cross-sectional region with embedded reinforcing long fibers, and at least one cross-sectional portion without reinforcing embedded long fibers.

A wheel component of a bicycle, including a spoke nipple with a nipple body and two opposite end portions remote from one another, to detachably connect a spoke of a wheel with a rim or a hub of a wheel. One of the end portions forms a nipple head. The nipple body has a takeup for an end of a spoke. The takeup includes a thread for fastening a spoke. The nipple body is manufactured from a fibrous composite material and includes reinforcing elements and at least one matrix material. The nipple body includes a tool receiving element to enable setting and adjusting the spoke tension.

The present disclosure provides an integrally formed carbon fiber spoke and a manufacturing method thereof. The method includes manufacturing a carbon fiber core body and a first metal part and a second metal part at two ends; winding or wrapping the carbon fiber core body and the metal parts at the two ends with carbon fiber prepregs to form a semi-finished product; and putting the wound or wrapped semi-finished product into a forming mold for heat forming. In the present disclosure, the metal parts are wound or wrapped with the carbon fiber prepregs, such that sandwich structures are formed between the metal parts and carbon fiber materials to expand a bonding force of bonding interfaces.

A nipple assembly for a spoke wheel according to the present disclosure is coupled to at least one end of a spoke provided on a spoke wheel and includes a main body including a nipple head, and a column portion having a smaller diameter than the nipple head and elongated from the nipple head toward one side, a nipple base having a first through-hole and fitted with the column portion through the first through-hole, and a vibration attenuation member having a second through-hole and positioned between the nipple head and the nipple base by being fitted with the column portion through the second through-hole.

A bicycle wheel assembly structure includes an annular rim, a hub, nipples, and spokes. The annular rim includes multiple rim penetration sections, each of which includes a rim-side limiting part on a circumference. The hub is arranged at the center of the annular rim. The hub includes multiple hub penetration sections. The rim-side limiting part and the nipple limiting part, and also the hub-side limiting part and the spoke limiting part, are all made in a hexagonal pyramid form with apex truncated to form a planar surface and including bevel facets so as to provide an anti-sliding effect resulting from geometric constraint and high static friction at both the annular rim-side and the hub-side. The angle of the hexagonal pyramid of the nipple limiting part is 60, 90, or 120, and an optimum arrangement can be made based on the material elongation of the spokes and the desired tension.
