so, i just completed a full upgrade / modernization of this bike:



Campagnolo drivetrain with NOS 9-speed Chorus brifters, "Racing Triple" rear derailleur, Campy 9-speed chain, and Record 9-speed cassette.
NOS Sugino Dynamic Pro chainrings (re-spaced for narrow 9-speed chain)
Velo-Orange Diagonale 650B wheelset
New Dia-Compe ENE NGC-999 cantilever brakes with Velo-Orange adjustable brake pads
Velo-Orange Grand Cru stem & leather bar tape
Nitto 45cm B135 "randonneur" bars and silver handlebar plugs
Zunow pantographed Suntour Superbe seatpost
Nifty retro LED flashlight with rack clips
New VIA chainstay slap guard and saddle bag clips

The ride is amazing. I've never ridden modern Campagnolo before, and it's better than I imagined. This is now not only the best bike I own, but the best-riding. I'm ready to put some serious miles on this guy.
