Claim:
A bicycle hub assembly comprising: a hub-and-axle subassembly including an axle extending along an axis and having a threaded end segment, a hub shell rotatably mounted relative to and surrounding said axle, and an antifriction bearing disposed between said hub shell and said axle to minimize rotational friction therebetween; a fork dropout having a pressing surface which is axially tightened toward said hub-and-axle subassembly from an untightened position; and a locking collar configured to couple said hub-and-axle subassembly to said fork dropout to lock said antifriction bearing in place, and including: an outward pressed surface configured to confront said pressing surface of said fork dropout; an inward abutting surface which is axially opposite to said outward pressed surface, and which is configured to confront said antifriction bearing; an axially extending female threaded surface which is configured to be screwed on said threaded end segment of said axle so as to bring said inward abutting surface into abutment with said antifriction bearing to place said outward pressed surface in the untightened position; a tubular extension extending from said outward pressed surface, and configured to be insertable into said fork dropout; and a plurality of circumferentially extending rib segments which are disposed on said outward pressed surface to be in pressing engagement with said pressing surface of said fork dropout in a tightened state.
