The odd brake boss placement on this frame indicates the use of Paul Component 'Racer' center pull caliper brakes. The front bosses are overlapping the Pacenti crown a bit....not and easy attachment and I will try to talk folks into another combination in the future, either a different crown or a center mount version of the brake. The crown is too nice to obscure it with the brake bosses, at least in my opinion.
That said, it will be a distinctive bike. There's a third set of bottle bosses and the chainstays are longer to accomodate a larger tire, most likely the Bruce Gordon 'rock 'n road' 700x43. These tires are gaining in popularity.
No problem with tire room here......more than needed in this case.
