I had a rear spoke break a while ago. Not being good with that sort of thing I stopped riding right away and took the wheel to my LBS. When I got it back and went to install it on my Specialized Allez Triple it went on fine but now every gear gives me a pronounced rubbing sound like what you might get from a FD when going from big chain ring to biggest cog as the chain rubs the cage. The sound if defiantly coming from my RD (Tiagra 9 speed). The sound is only there when I peddle and the hub/wheel spin freely with no odd sounds. Before I took the wheel in my drive terrain was whisper quiet. It almost sounds like it wants to jump into a different cog but I can see no place where it is rubbing.

Any ideas would be great. I don't know a whole lot but I did check Sheldons site and saw nothing that was of use to my situation.
