Abstract
A bicycle hub is provided with spoke openings that extend into the interior of the hub. The bicycle hub basically has a hub axle, a hub body and a seal arranged in the hub body. The hub axle has a center axis extending between a first end and a second end. The hub body has an interior passageway with the hub axle being rotatably supported therein. The hub body also has a set of first spoke openings circumferentially arranged around one end of the hub body and a set of second spoke openings circumferentially arranged around the other end of the hub body. The spoke openings of the hub body are arranged for use with tangential bicycle spokes having a straight section and a bent end with an enlarged head such that straight section extends at an angle of about 95° relative to the bent end. A first seal is arranged in the interior passageway of the hub body and adjacent the first spoke openings to isolate the first spoke openings from the hub axle. A second seal is arranged in the interior passageway of the hub body and adjacent the second spoke openings to isolate the second spoke openings from the hub axle.
