I have a Campagnolo Record 10 speed setup that I purchased slightly used but in nice shape. The rear derailleur has pretty red Token tiramic jockey wheels installed. It seems that no matter how much cleaning & re-lubricating I do, there is an annoying squeak that comes from the jockey wheels after about 30 miles or so. Every time I have thought that I have it all clean/lubed enough, it comes back. Is this something common with these jockey wheels? I had the same bike built up with all the same parts but a different Record 10 RD (Campy jockey wheels) and there was no squeak. I have the original jockey wheels and I'm thinking of putting them back on if I can't kill the squeak with the final round of ultrasonic cleaner & ice wax that I'm doing right now on the chain..just wondering if anyone else has run into this and if so, what did you do to 'fix' it...or, is the squeak a sign the aluminum is worn? I haven't tried a different chain yet either but the chain didn't squeak before...

thanks for any insight.
