A bicycle hub is provided with a hub axle assembly, a hub shell and a pair of
bearing
units. The hub axle assembly basically has a hub axle washer, a bicycle hub axle
and a washer retaining portion or member. The hub axle washer includes an outer
peripheral surface and an inner peripheral surface defining an axle receiving opening.
The bicycle hub axle includes a shaft portion and a head portion with the washer
retaining member or portion being located on the shaft portion to retain the hub
axle washer on the shaft portion. In the preferred embodiment, the washer retaining
portion or member is a resilient member in the form of a flexible O-ring.
