<p>A bicycle hub includes a hub body (1), an inner member (2) coupled to the hub body (1) for rotation therewith, and an outer member (10) disposed about the inner member (2) for rotation relative to the inner member (2). The outer member (10) is adapted to be coupled to a chain gear for rotation therewith. A plurality of clutch rollers (11,12) are disposed between an outer circumferential surface (2a) of the inner member (2) and an inner circumferential surface (10a) of the outer member (10). The outer circumferential surface (20) of the inner member (2) and the inner circumferential surface (10a) of the outer member (10) are shaped so that when the plurality of clutch rollers (11,12) are disposed in a first position the inner member (2) and the outer member (10) rotate together, and when the plurality of clutch rollers (11,12) are disposed in a second position the inner member (2) and the outer member (10) can rotate relative to each other. <MATH></p> |
