I'm wondering about this direction too, for this bike:
I have no idea what wheels it had originally. I put 700C wheels and 25mm Paselas on it. But the BB is about 1cm lower than what I'd consider typical of my other bikes. If it was built for 27" wheels and 1 1/4 tires, it would ride maybe 1cm higher. It handles a bit oddly, sort of feels like it doesn't want to turn without significant encouragement. Perhaps that's just what a medium-priced French bike built in Belgium in 1972 should feel like. Or perhaps it would feel different if it rode higher.
FWIW too, I put Mafac Racers on it, and they do like to squeal. A larger wheel would put the shoes closer to the arms' pivots and perhaps stabilize them.
Thoughts, anyone? Yeah, I know, you're probably going to say it won't make any difference.
