Yeah, but I don't have that Goldilocks feeling on 700c, so I question the notion of "just right." I did see one attractive bike on the 650b advocacy page (I don't remember which) which had a short-wheelbase racing bike with 650b wheels. Sure, you compromise the tautness with the smaller, fatter wheels. I can see that. But I wouldn't see the point on a touring or sports-touring bike.

I suppose we could talk all day about this. I've been riding 27" and 700c for a LONG time, usually with narrow tires, and I think I'm too old and set in my ways to learn to appreciate smaller or wider wheels now.
