For me, it's this one. 1965ish Cinelli SC frame, 1960ish Cinelli SC fork (long story told elsewhere so I won't repeat it here) with Campy 10sp triple drivetrain (mix of Record and Chorus). The newest one in the barn, the best bike I have ever had, bar none, and it';s the one I reach for almost every time out. It also has the rattiest paint by a lot,
