Abstract
A bicycle hub assembly has a hub axle with a nut, a hub shell rotatably support the hub axle by a bearing assembly disposed between the hub axle and the hub. The hub axle and the nut form a bicycle hub axle assembly that is especially configured to permit easy removal and/or installation of a rear derailleur. The hub axle includes a shaft portion having a threaded section at a first axle end and a head portion fixed to a second axle end. The nut has a body portion with a projection extending axially from a frame engaging surface, and a threaded bore threadedly engaged with the threaded section of the shaft portion to secure the bicycle hub axle assembly to the bicycle frame. The projection is configured to engage a slot in a bicycle frame to prevent rotation of the nut relative to the bicycle frame.
