You changed what from 9-speed to 10-speed? Everything?

okay....a little more information is necessary i'm guessing. i just bought a new bike. campy record 10sp. 53-39 double on the front. ut crank. when on the small ring in front and crossing up to the lower cogs on the back is it normal for the chain to rub the big ring enough to make a rattling noise? and no, it is not rubbing the deraileur.
thanks
thanks

What you are describing is a "cross over" and you never should do that, or even have a reason for doing it. You can get beter gear ratios by other means. I think it strange that you have never heard about this.

duh, of course i've heard about crossover....but only on triples. my 9sp never had this going on, but the two front rings are a little wider spaced than on this newer bike. and it does this on the second smallest cog as well. guess i didn't really need a 10sp if it only has 9 working gears.
