Could the part marked in the red circle be refered to as "flange", or does that word only apply for the place were the drillings for the spokes are?. I bought a bike with an extra spare wheel, knowing that that wheel had a "missing flange" (i was told that it could be fixed just by replacing it, so i thought it was the part in the red circle, and that's no big deal). When i got the wheel, i saw that one of the silver parts was missing, and i was ok with it because i knew that was the missing part. A few seconds later i noticed that two of the holes for the spokes were busted, and i got a little upset... I began to write an email to the seller, and after some lines i realized that since i'm no native english speaker, this could well be an idiomatic problem, so i decided to ask you guys to help me clarify the english terminology for hub parts before sending that email..
