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 seals 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 first and second spoke openings circumferentially arranged around the ends of the hub body. 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 seal support is located beneath the first seal to prevent radial inward movement of the first seal. 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. Preferably, the spoke opening covers are located in grooves of the hub body to seal the insertion portions of the first and second spoke openings.
