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 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 composite rim for a bicycle wheel that has a wall of structural fibers incorporated in a thermosetting polymeric material and a plurality of spoke attachment seats. The composite material includes at least one layer of woven bi-directional fibers where some fibers are in a nominal direction substantially parallel to the circumferential direction of the rim and some fibers are substantially orthogonal to the circumferential direction of the rim.

A nipple for spoked wheels includes a head and a rod which are coaxial and through which a through-hole extends, a manoeuvring key in the head and an insert of plastics material which is inserted in the hole in order to engage in a screwing manner with friction with a threaded end of a spoke. The hole comprises a threaded portion which extends in the rod and a portion with an increased diameter which constitutes the seat for receiving the insert, the insert being formed with a tubular sleeve inserted in the seat at the side of the head and being blocked there by means of interference or adhesive bonding.

A rim for a bicycle wheel includes a radially inner portion disposed along an inner circumference of the rim. The rim also includes a first sidewall and a second sidewall spaced apart from the first sidewall. The first sidewall and the second sidewall extend radially outward from the radially inner portion. The first sidewall includes a layer of a composite material. The layer of the composite material includes fabric plies of the composite material that are shaped as strips. The composite material includes a matrix of a polymer-based material and fibers of a reinforcing material. The strips include a first strip and a second strip. The second strip is adjacent to the first strip within the layer of the composite material. The second strip is nonparallel to the first strip.

A spoke wheel for a straddle-type vehicle includes a rim having an outer peripheral surface on which a tire is mounted and an annular shape, a hub supported by an axle on an inner side of the rim and having a tubular shape, and a plurality of wire spokes connecting the rim to the hub. The rim is formed with a plurality of spoke holes through which the plurality of wire spokes pass and support surfaces receiving head portions of the plurality of wire spokes on one end sides of the plurality of spoke holes. Each of the support surfaces has a groove shape extending in a wheel rotation direction.

A bicycle rim printing apparatus comprises a non-contact printer to print a non-contact printed deposit to an annular rim body, a rim holder to hold the annular rim body, and a rotational actuator to rotate the rim holder relative to the non-contact printer about a rotational axis.

An intelligent automatic processing apparatus for spoke holes of bicycle rims is revealed. The apparatus includes a seat pivotally connected to a machine body and provided with a rotary base. A rim is clamped and fixed by clamping jaws on the rotary base and a control unit drives an incline unit to incline the seat connected at an angle desired for control of slopes of holes being drilled. The control unit also drives a rotary indexing power source to rotate the rotary base at different angles according to the numbers and positions of spoke holes desired. Thus a drilling assembly drills the spoke holes on the rim. Thereby the spoke holes with various angles can be drilled on different positions of the rim by the control unit which adjusts positions and inclination angles of the rim accurately. Therefore, the drilling of the spoke holes is more convenient.

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 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.
