I recently opened up the hubs of my 2004 Campagnolo Proton wheels, and re-greased them for the first time with Castrol LM grease (the experts say it doesn't matter within reason what you use, as long as you do it). They weren't clanking, or dry, before, and there not now.

From what you said, I think the rear wheel probably just needs greasing and re-adjusting
Thanks. I have never hear the clanking before on any bike. Quite disconcerting.
