My wife is selling her 1980s Colnago Export with campag groupset. Its a 48cm frame and is just too small for her (she’s around 5ft8") despite about a year trying to convince herself that it isn’t. (It also doesn’t fit the fancy new direct drive turbo I just bought. Oops). Bought it from steel-vintage.com for around €1,000 2 christmases ago.
The only change she made was getting Seabass cycles to fit a slightly less brutally geared freewheel (and longer rear mech cage to accommodate) but have all the original parts).
