A rim includes a rim body and a spoiler portion. The rim body is annular and has two opposite side surfaces connected by an intermediate portion. Each surface has a radial inner portion located on a radial inner side and a radial outer portion located on a radial outer side. The radial outer portion has an extension portion and a radial outer periphery at the outermost side. The extension portion is extended toward the radial outer side from a connecting portion between the radial outer portion and the intermediate portion. The spoiler portion has a plurality of spoiler profiles concavely formed on the radial outer portion of at least one of the two side surfaces. At least one of the spoiler profiles is partially disposed on the extension portion without forming any undulation on the radial outer periphery.

The present disclosure may relate to centerless wheel assembly that includes a centerless rim including a first center point laying in a first plane generally defined by the centerless rim. The centerless wheel assembly may also include a centerless ring gear coupled to the centerless rim such that rotation of the centerless ring gear causes a corresponding rotation of the centerless rim. The centerless ring gear may include a second center point laying in a second plane generally defined by the centerless ring gear, and the first plane may be generally parallel to the second plane. Additionally, the centerless ring gear may be shaped to interface with a drive gear that drives the centerless ring gear.

An article, such as a bicycle wheel (10), includes a substrate, at least a surface of the substrate being made of or containing a composite material comprising fibres dispersed in an organic matrix, for example a carbon fibre composite. A thermal sprayed first layer of coating material is provided on the surface, such as the braking area of the rim of the bicycle, the coating material of the first layer wholly comprising inorganic material and including at least one of the group comprising TiO2, titanate, Al2O3 and aluminate.
摘要:
A bicycle rim is provided with a pair of circumferential side walls and an outer bridge connecting radial outer ends between the first and second circumferential side walls. At least one of the first and second circumferential side walls includes a first portion of a non-resin material with a first thermal conductivity and a second portion of a non-resin material with a second thermal conductivity. The second portion extends more than half in a circumferential direction along the at least one of the first and second circumferential side walls. The second thermal conductivity of the second portion is higher than the first thermal conductivity of the first portion. The first and second portions at least partially overlaps in a thickness direction of the at least one of the first and second circumferential side walls.
