jaseyjase, I like that.
I've decided that after much deliberation, I'm going to proceed and put STIs on my beloved old McLean. It has had Campagnolo Nuovo Record and Super Record all of its life since 1983. It will be a mismatch, and it will even be a slight insult, because I'll be using Tiagra. But the price was good, and I expect it to work well. Pictures will follow. First, I have to take some really nice "before" pictures. I haven't started the project yet.
