A bicycle hub includes a wheel securing structure having a retaining
arrangement disposed with respect to the hub axle and a wheel securing
shaft member. The retaining arrangement overrideably prevents the shaft
member from being axially removed from the hub axle when in a
predetermined position within the through bore of the hub axle. In other
words, the retaining arrangement is arranged to releasably restrict
relative axial movement between the shaft member and the hub axle when
the shaft member is disposed in the through bore of the hub axle in a
predetermined position so that unintended displacement of the wheel
securing shaft structure from the hub axle is prevented during use of the
wheel securing shaft structure.
