A vehicle wheel includes a rim having mounted thereon an inflation valve and a tire. The inflation valve is extended by an inflation channel extending through the rim and opening out into a volume of gas defined by the rim and the tire. The inflation valve is arranged in the vicinity of a flange of the rim.

A rim (3) for a rolling assembly has a flexible extender, the rim having an axis of rotation DD′, said rim having a rim seat (31) extended axially towards the outside by a rim flange (32), said rim flange (32) having a first portion (321) that is oriented substantially in a plane perpendicular to the axis of rotation DD′ and situated radially on the outside with respect to said rim seat (31), said first portion (321) being extended radially and axially towards the outside by a connecting portion, characterized in that the radial height measured between the intersection point between the line of the rim seat and the line of the first portion, and the end of the radially outermost portion of the rim flange (32) is less than 10 mm.

A rolling assembly includes a tire having two beads, a rim and a flexible extender intended to provide the connection between one of the beads and the rim, the rim having a rim flange, the extender including an axially inner end, an axially outer end and a body oriented mainly axially and disposed between the axially outer end and the axially inner end, the axially inner end being fixed in place on the rim, the extender having an extender seat intended to receive a tire bead, the extender seat being extended axially towards the outside by a shoulder that axially fixes the tire bead in place, the tire bead having an axial width WB at the interface of the bead with the extender seat, characterized in that the rim flange extends axially under the bead by a distance S such that the ratio S/WB is greater than 0.1.

An internal double beadlock system includes a centralized inner ring and one or more tire positioners. The one or more tire positioners are coupled to extend out from each side of the centralized inner ring. Each of the tire positioners has a length to detachably engage with a portion of an inner tire wall on each side of a tire positioned on a tire rim while being shorter than a width of the tire rim.

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, a second sidewall spaced apart from the first sidewall, and a radially outer tire engaging portion disposed along an outer circumference of the rim. The first sidewall, the second sidewall, the radially outer tire engaging portion, the radially inner portion, or any combination thereof includes a composite laminate. The composite laminate includes a layer of a composite material. The composite material includes a matrix of a polymer-based material and natural fibers of a reinforcing material. A volume of a respective one of the natural fibers of the layer of the composite material is greater before lamination of the composite laminate compared to the volume of the respective one natural fiber after the lamination of the composite laminate.

A wheel rim includes a rim body, two flanges and two reinforcing structures. The rim body surrounds an axis and is made of carbon fiber composite material. The flanges protrude radially and outwardly from an outer peripheral surface of the rim body, spaced apart from each other along the axis, are made of carbon fiber composite material, and define respectively two spaces therein. The reinforcing structures are respectively received in the spaces, and each of the reinforcing structures includes a plurality of fiber bundles fixed in a respective one of the flanges. Each of the fiber bundles includes at least two strands of carbon fibers being twisted.

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.
