I know some of this was just discussed, but I have a rear Mavic deemax 05 rear hub that when I was using it made a sort of humming noise, especially on fast flat sections; I don't know that the hub ever spun slower, but it was really annoying. There were some other issues from the rear end of that bike, but I was sure it was the hub. Anyway, now the wheels been off a bike for awhile, I was spinning it in my hands and the hub spins fine; could the hub be ok? and anyway, how would i fix it?
