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 method for manufacturing self-locking nipples comprising the steps of providing a semi-finished nipple (10) with an enlarged head (5) in comparison with the shank (6), providing at least a first blind hole (11, 11a) in that head, injecting a fluid resin into the hole (11, 11a) and solidifying so as to obtain a corresponding insert (9, 9a), making a second axial hole (7) in the semi-finished product at least partly intersecting the said insert (9, 9a).

The invention relates to a drive wheel for a bike, comprising a rim which is fastened to a hub by means of a plurality of spokes, wherein the spokes are made of reinforcing fibers embedded in resin, the reinforcing fibers of a spoke extending from a first fastening portion at the rim to a second fastening portion offset against the former in the circumferential direction and being guided along the outside of the hub, wherein the hub takes a shape polygonal in cross-section on the outside to which an axial side of each spoke is adjacent. The invention further relates to a bicycle comprising said drive wheel configured as a rear wheel.

A vehicle wheel having a rim, a hub, a plurality of spokes with at least one of the spokes having a first portion connected the rim and a second portion connected to the hub. The rim includes a spoke bed wall with a radially outboard surface and a spoke hole having a radially outboard entrance and perimeter edge. The spoke extends through the spoke hole and is engaged to the spoke bed wall by an overlie engagement at a bearing interface between a bearing surface of the spoke and the radially outboard surface to limit longitudinally inward displacement between the spoke and spoke bed wall. At least a portion of the bearing interface is laterally outwardly spaced from the first perimeter edge by a lateral distance of at least 0.7 millimeters.

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.

A rim for a bicycle wheel includes a radially outer tire-engaging portion, a first sidewall, and a second sidewall spaced apart from the first sidewall. The first and second sidewalls may extend radially inward of the radially outer tire-engaging portion. The rim includes a radially inner portion having at least one asymmetric protrusion.

A bicycle wheel has a wheel frame. The wheel frame is a hollow and annular frame and is composited by multiple equally sized wheel bars. Each one of the wheel bars has two halves connected to each other to form the wheel bar, and each one of the two halves being made by laminating, heating and forming a thermoplastic prepreg. The equally sized wheel bars are connected to each other to form the bicycle wheel.

A spoke attachment assembly configured to couple a rim to the spokes of a spoked bicycle wheel. The spoke attachment assembly comprises a nipple having an enlarged head and a stem provided with a coupling portion for coupling with a spoke, at least one shaped washer associated with the nipple and configured to abut on one side with the enlarged head of the nipple and, on the opposite side, with the rim and holding means configured to hold said at least one shaped washer associated with the nipple. The invention also relates to a spoked bicycle wheel and to a process for manufacturing such a wheel.

A process for manufacturing a spoked bicycle wheel, comprising the steps of providing a rim element having a spoke attachment chamber; providing a spoke attachment assembly for coupling to a respective spoke, inserting the spoke attachment assembly through an opening of the spoke attachment chamber along an insertion direction that is inclined with respect to the rim element and moving the spoke attachment assembly along the insertion direction until a stem of the spoke attachment assembly is at the surface of the spoke attachment chamber; moving the spoke attachment assembly along the surface of the spoke attachment chamber towards a spoke attachment seats; inserting the stem in the spoke attachment seat; and, constraining the spoke attachment assembly in the spoke attachment seat. The steps are repeated to couple a respective spoke attachment assembly to each of the plurality of spoke attachment seats. The invention also relates to a spoked bicycle wheel produced by the above process.

A vehicle wheel including a rim, a hub, and a plurality of spokes extending with a span portion between the rim hub. The rim and/or hub constitutes a bracing element. A connecting element is connected to the bracing element and includes an external surface, an internal cavity. A spoke has a longitudinal axis and an external spoke surface that that overlaps the internal cavity in an overlap region, and a pre-formed lateral spoke surface. The connecting element is crimped to create a crimped joinder with the spoke such that the connector surface is pressed and plastically deformed to displace the internal cavity toward the spoke surface in the overlap region to cause a lateral connector surface to laterally overlap the lateral spoke surface to create an overlie engagement and/or to increase a lateral overlap between a lateral connector surface and the lateral spoke surface in an overlie engagement. The overlie engagement supports spoke tensile load.
