Wow, it puts my 1981 Davidson to shame. I'm the original owner and I took it out today to Central Park. It still has the original headseat, Campy NR shifters and rear derailleur, bars, stem, Zeus bottom bracket but not the crank. Just about everything else is more modern. 10 speed wheels, dual pivot brakes, carbon seat post, Campy Chorus 10sp crank (square taper, same as Zeus!) I tried replacing the bottom bracket but I couldn't get the fixed cup off. I repacked it and it is as smooth as anything I've ever been on.
