Abstract: A bicycle wheel rim having rim walls joined at their proximal ends by an inner annular bridge, an annular outer bridge disposed at the approximate midpoint of the rim walls, and a vertical beam disposed between the outer and inner bridges.

Abstract: A tire assembly for insertion into a tire mold including a partially cured base tire and a partially cured skin. The partially cured base tire includes a plurality of spaced tread members. The skin includes a predetermined percentage of reinforcing fiber comprised of a crushed mono-filament aramid fiber material and the skin includes a predetermined printed pattern. The partially cured skin is at least slightly larger than the partially cured base tire and surrounds and engages an entire outer periphery of the partially cured base tire. The partially cured skin surrounds and engages an entire tread surface of the tread members. The partially cured base tire and the partially cured skin are insertable into the tire mold. The predetermined pattern is visible on an external peripheral surface of the tire assembly.

Abstract: The present invention, in one embodiment, is a method of making a tire with a skin covering at least a portion of the outer peripheral surface of the tire. In practicing the method, a partially cured tire and a partially cured skin are provided. The partially cured tire and the partially cured skin are installed in a tire mold with the skin engaging and covering at least a part of the outer surface of the tire and with the skin facing an inner surface of the mold. Heat and pressure are applied to the tire to press the skin and the tire against the inner surface of the mold. The heat and pressure are maintained for a predetermined time period to vulcanize and bond together the tire and the skin.

Abstract: The present invention relates to a tire rim for wheels of cycles in general adapted to allow an easy and firm assembling of the tire, and has the main feature that the rim comprises a body the cross-section of which defines a well for the tire, laterally delimited by ridges adjoining recesses for the tire bead, which recesses are delimited on their outside by a hook portion or rim flange having a top inwardly curved crook portion.
