ABSTRACT:
A hub assembly for a bicycle wheel is provided which includes a hub shell and two ball cups. The hub shell has two flat rod ends at respective ends of the hub. An arched portion is formed at a bottom portion of each flat rod end. A hub flange is formed on the inside of each flat rod end at the base of an arched portion, and a flare extending from inside of the hub flange to a center portion of the hub is provided. The ball cup has a hollow tapered journal and a shoulder hole formed therein to divide the tapered journal from a flared ball cup at the other end. In assembly, the ball cup is fixed into the hub by a force fit between the outside surface of the ball cup and the inside surface of the flat rod end, the flare clamping the tapered journal, and positively locating the ball caps within the hub.
