Here you go, 4 easy steps:
1) completely remove derailleur,
2) throw in trash,
3) remove other components and throw in trash,
4) replace with Campagnolo.

Have fun!

Harvey, dont be intimidated by snooty campagnolophilles.
what you want to do is move your derailleur slightly outwards untill the rub goes away. to do this, tighten your cable, since it has probably stretched since it was new. The easiest way to tighten your cable is to turn the barrel adjuster on your downtube outwards, probably just a turn or two. That should take care of it. Be careful, if you turn the barrel too much the chain wont downshift properly - it can be a real balancing act sometimes. IMHO, A little bit of rub is ok when your down on the lowest cog - that just tells you its time to get into the big ring.
Also, make sure that your derailleur is parallel to your rings before messing around with the cable tension. good luck!

Did it ever work right?Spoke Wrench

I basically agree with Dave.

If it ever worked right, you have a stretched shift cable. In spite of what you may have heard, this happens with Campy components too. I think that a mistake many novices make is to adjust the cable too much at a time. I rarely adjust cable tension more than 1/2 turn at a time. Turning the barrel adjuster counter clockwise will increase your cable tension.

If it never worked right, it could be the position of the derailleur on the seat tube or the low gear limit screw adjustment. Quite honestly, this isn't the easiest adjustment on a bike for a novice to start with. Since this is a pretty new bike, I'd take it back to the guy who sold it to me and ask him to fix it.
