A rim for a mountain bike is provided, including a rim body having a rim well, a rim base and two lateral rim flanks and a hollow space device with a hollow space. A width of the rim body is larger than 30 mm. The hollow space device of the rim body is radially outwardly limited by the rim well and laterally and radially inwardly, by an inner enclosing wall including the rim base and the rim flanks. The radially inwardly enclosing wall forms an internal wall that is substantially closed, apart from the nipple accommodations. The rim well includes a plurality of recesses having a surface proportion of at least 10% of a surface of the rim well.

Herein is disclosed a rim for a wheel. the rim comprising a barrel having first and second flanges extending radially outward from opposing edges of the barrel. and the barrel comprising a first bead seat and a second bead seat arranged axially inwardly. respectively. of the first and second flanges, wherein the barrel, and first and second flanges. comprise layers of structural fibres bound in a polymer matrix, wherein a pre-form insert is disposed between layers of the structural fibres. wherein the insert comprises a material which acts to absorb and/or deflect and/or dissipate energy from a load or impact applied axially and/or radially to a rim and/or acts to increase the hoop stiffness of the wheel and wherein the insert has, when viewed in cross-section (with the axis of the rim being parallel to the plane of the cross-section). two elongate portions. with a first elongate portion of the insert extending into one of the first or second flanges. and a second elongate portion of the insert extending underneath the first or second bead seat, respectively, such that first and second portions together form an approximate L shape in cross-section.

A bicycle wheel rim having a circular base portion including a proximal surface and a distal surface, and a pair of integral sidewalls extending generally radially outward from an intersection region of the proximal surface and the distal surface. The distal surface of the rim has a central hump, a trough contiguous with the central hump extending axially outward from the hump, and a flat shelf immediately adjacent, contiguous with, and extending axially outward from the trough. Another embodiment of the invention is directed to a bicycle wheel including the embodied rim, a plurality a spokes engaged at respective ends thereof with the rim and a hub engaged with the plurality of spoke members at opposite ends thereof. Another embodiment of the invention is directed to a bicycle wheel assembly comprising the embodied wheel and a tube and/or tire mounted on the rim.

This disclosure concerns wheels for industrial vehicles, including scissor lift vehicles and aerial platform vehicles. More particularly, this disclosure concerns a wheel fabricated with a substantially cylindrical wheel rim and a front face surface which includes a center hub section that is inwardly offset from the front edge by an amount and at an angle providing flexibility to recover from incidences that can damage the wheel.

A rim assembly for a bicycle wheel, comprising a rim having generally opposing first and second wall sections configured for mounting a bicycle tire, each of said first and second wall sections comprising an outwardly facing recess and; a rim component located in each recess, wherein each rim component has a lower density than the rim, wherein the rim components do not form part of a braking section of the bicycle wheel.

The invention relates to an aircraft wheel comprising a rim and a tire (20) received on the rim, the rim comprising two parts (1; 2) assembled with one another by means of assembly bolts (5), one of the parts comprising a recess (3) in which is arranged a seal (4) which is interposed between the two parts, the wheel being characterized in that at least one of the parts comprises at least one duct (6) extending beneath the seal so as to establish a leakage path between on one hand a volume of gas delimited by the rim and the tire, and on the other hand a space between the parts, the path being nominally closed by the seal when the bolts are tightened correctly but allowing gas to leak from said volume when the bolt associated with said opening is not tightened correctly or is absent.

A bicycle wheel including a hub and a rim coupled to the hub. The wheel also includes a cover that is coupled to rim and that defines a bead seat engageable by a tire. The rim can have a first annular feature and the cover can have a second annular feature that is complementary to the first annular feature to attach the cover to the rim.
