i know that the falcon rear hubs are a cheaper line, but that is what i had and am using on my latest build. the problem i had was when i was not peddaling, there was a awful "growling" noise coming from the hub. i took it apart, found what i thougt was a dry enough bearing to cause it and no luck, still growled. so after taking it apart a dozen times i finally seen it! the sprocket side where the brake cone tightens up to inside of the hub when you pedal had teeth marks worn into the hub from the cone and when you werent pedaling and it backed off, the teeth on the the cone and the worn hub would rub and make the noise!!! so after honing it with a wheel cylinder hone and sanding it smooth w/sand paper i finally got it quite!!!. just thought i would share in case some one else runs into the same problem.
