Spacer on wheels

Did you also switch from Shimano to Campy?
Campy uses wider spacing on it's cassette.
Some wheels space the cassette closer to the drop-out to keep the chain away from the spokes.
Your dealer should care for these details.
Peter Chisholm and Andrew Muzi are regular contributors here and both sell Campy and know how to deal with the details.

Well, I've done this in the past, but not in several years. Really, the cassette should be in the
same position on both wheels. You should be able to swap wheels and go, without having to even
adjust your derailleur (of course, this presumes that both are meant for the same
derailleur/shifter).

It would seem that the new wheel has the cassette too far to the right, but it's hard to tell
without seeing it. Some bikes don't have enough clearance for the chain.

OTOH, if you are going to keep using this wheel, only, the spacer won't mess things up. Ideally you
should adjust the dish, but this is within 1mm, so not worth the trouble.

Campagnolo have carefully stuffed about as many gears as they can into as small a space as possible.
Your Neutron wheels are pretty much sorted "right from the box".

One assumption Campy might be making is that nothing protrudes inward from the inside face of the
dropout. (The hanger? The tip of the derailleur's mounting bolt?)

It may be your Giant's hanger (removable, right?) or your derailleur's mounting bolt is part of the
problem. If so, I'd consider shaving those parts rather than use a washer. That way the wheel is
interchangeable with others.

There is something wrong with the frameset. You should not have to add a spacer to any frameset to
prevent rubbing when using a Campagnolo hub.

Is the freehub tight, the locknut(left threaded) that holds it on tight? Is the cogset tight?

This should not happen.

Don't you go running him off, now; we need him to keep things in perspective when the technocratic
nerves start to get rubbed raw.

Getting back on the original topic, though, I have to wonder if there's any possibility that the
bearing cone's locknut might have been missing on the right side. On the one and only occasion that
I bought a *new* wheel from an lbs, it was missing one of the locknuts. I caught it when I went to
check to make sure the bearings were properly greased, and the lbs supplied one without grousing,
but I have to suspect that they had scavenged it to fix a bike and then forgot to replace it. Of
course, I wouldn't expect this to be easily overlooked; generally, just spinning the axle will
completely screw up the bearing adjustment if the locknuts aren't both at least snug.
