Hmm, true. I think the clearance between cup and crank is supposed to be around 0.2mm. However, based on the fact that I've never seen Italian versions of SRAM or Truvativ cranks with longer spindles, I bet they've taken that 1mm out of the width of the cup itself, to keep everything compatible with the same spindle. If not you could probably have the LBS face away 2mm, which might create compatibility issues later- nothing that couldn't be fixed with spacers though.

Thanks for everyone's input. I just ordered a Campy C Record crankset and a Campy Pista BB. I hope I get lucky with the chainline like some of you guys had mentioned. All this worrying about chainline is NOT getting my bike built. Hopefully ignorance is bliss!
