A vehicle wheel having a rim part to which a tire is mounted and a vehicle body attachment part which is attached to a vehicle body, in which the rim part has, on an inner circumferential surface thereof, a plurality of fins each having a heat dissipation surface, and in which the fins are arranged periodically along a circumferential direction.

A structurally supported tire includes a ground contacting annular tread portion, an annular hoop structure for supporting a load on the tire, a means for attachment to a vehicle rim, and a ply structure secured to a first axial limit and extending radially outward and between the hoop structure and the tread portion and further extending radially inward from between the hoop structure and tread portion to a second axial limit. The ply structure is secured to both the first axial limit and the second axial limit. The tread portion is secured to a radially outer surface of the ply structure. The hoop structure is secured to a radially inner surface of the ply structure.

A wheel for use with a bicycle includes a hub for mounting the wheel to a bicycle, a rim about which a tire is mountable, and a plurality of spokes that extend between the hub and the rim. The rim and/or one or more of the spokes have a leading and/or trailing edge, at least part of which has an undulating configuration.

An air valve connecting device includes a sliding member slidably engaged in a housing and having a pathway for aligning with a passage of the housing, and the sliding member includes a mouth for engaging with an inflation valve, a gasket is attached to the sliding member and includes a bore for engaging with the inflation valve, a latch device is slidably engaged in the housing and includes an opening for engaging with the inflation valve and for allowing the inflation valve to be engaged with the mouth of the sliding member, and the latch device is biased and forced to engage with the inflation valve with a spring biasing member for retaining the inflation valve to the housing.

A process for manufacturing a bicycle wheel component, comprising the steps of providing a component having at least one braking area that cooperates with a braking body made by molding of composite material having structural fibers in a polymeric material, and post-molding machining of at least one region of the braking area by removing only polymeric material, without removal of the structural fiber, from the entire region so that the structural fiber outcrops at least in part from the polymeric material, and removing the structural fiber and possibly the polymeric material according to at least one groove within the region. A bicycle wheel component having a braking area of composite material, wherein in a region of the braking area, the structural fiber outcrops at least from the polymeric material, and the region comprises a groove through the structural fiber and possibly the polymeric material of the composite material.

A vehicle wheel having a rim, or a rim of a vehicle wheel, is provided wherein the rim consists of a fiber-reinforced plastic material in the form of several layers of a fiber-reinforced semi-finished plastic product. The layers are shaped to form a finished component in a press while heat is supplied. The rim conventionally consists of a rim well, whose two sides are adjoined by a rim shoulder, which transitions into a rim flange. The rim well is formed by several layers of a base laminate, which extends to the rim flange, between which layers further layers are inserted in the area of the rim shoulder as well as of the rim flange. The further layers have an essentially tangential fiber alignment.
