Abstract
A hub assembly for a bicycle includes a hub shell rotatably mounted on a hub axle, a plurality of pawls disposed respectively in retreat bores in the hub shell to be moved between driven and idle positions, a chainring carrier rotatably mounted on the hub axle, a surrounding drive member coupled with the chainring carrier and having an annular ratchet segment to be coupled with the pawls so as to form a uni-directional mechanism, and an annular barrier member that confronts an annular insertion opening in the hub shell, and a shielding member including a rim which is water-tightly engaged with the insertion opening, and an annular flexible web body which has a tubular tail portion that is kept in frictional contact with a protrusion of the annular barrier member.
