My exact question about your build is the same one that eschlwc put forward, with a 130 spread on the rear drops, you are into 8, 9, 10, and 11 speed width. The NR mech is going to be uncooperative about things, it wasn't designed for that type of set up.

That is one beautiful frameset, quite a good quality builder that you chose, just wanted to express a fear about what you say that you want to accomplish.

The Superbe brakes are first class stuff, I had a pair on my Raleigh International, no problems with setting them up, or with getting them to hold the setting. I used the washer shown above, and installed them carefully, loosened the mounting nut, pulled the brakes down on the wheel, and tightened the nut to spec. No issues ever with them, or any of the Campag side pulls for that matter. Buy the tool shown, set it up carefully and enjoy. the mech choice is going to be your bigger problem, IMHO.
