Abstract: Wire spoked tubeless wheel (1) is sealed and made airtight by forming the wheel rim well with a flat base (55) with countersunk holes (40) in the base to fully receive the spoke nipples (45) and applying sealing tape (60) to the flat base covering the countersunk holes (40).

Abstract: A wheel and floating rotor disc brake assembly including a wheel having a hub with at least one projecting portion, the projecting portion having a slot formed at least a part way around thereof, the slot lying in a plane substantially normal to the axis of rotation of the wheel and parallel to the plane of rotation of the wheel. The disc brake rotor has at least one radially inward protruding tab, adapted to locate in and be fixed to the hub slot via pin elements. Axial spring clips or thrust washers are retained between the hub and the disc brake rotor by the pin elements, thereby permitting a limited degree of axial movement, or float between them.
