Abstract:
1. A bicycle wheel hub body comprising: a central tubular portion that is formed of carbon fiber incorporated in a plastic resin and defines a through aperture about an axial centerline with first and second ends of predetermined interior and exterior diameters about the centerline and a predetermined thickness between the interior and exterior diameters; first and second end caps, each joined with and extending from a respective one of the first and second ends and having interior and exterior diameters greater than the predetermined interior and exterior diameters of the first and second ends and a thickness greater than the predetermined thickness between the interior and exterior diameters of the first and second ends, each of the first and second caps further defining a bearing seat and a circumferential spoke attachment location; and, a plurality of spoke receiving apertures positioned axially outward of the bearing seats, said plurality of spoke receiving apertures defined in each of the first and second end caps so that a spoke mounted in the aperture has a head portion positioned against the interior diameter of the end cap and at a greater distance-from the central tubular portion than the bearing seat; wherein the wall thickness of the end caps is continuously increasing extending axially outward from the bearing seat to the spoke receiving apertures.
