I'm glad I found this thread. I just bought a 90-91 Tommasini Super Prestige that I'm planning on putting modern components on. This thread gives me a lot of inspiration...
I do have a question, though. My bike has 126 mm rear dropout spacing, but obviously new rear wheels are 130 mm. I'm assuming since we're only talking about 2 mm on each side, that it won't hurt anything to put a wider wheel on, but I wanted to ask just in case. It's Columbus SLX tubing, by the way...
