You can't buy the whole bike? You certainly need to get a closer look. There area few difference in the frame, most notably the chroming of the crown, and decal colors but I believe that is a 1983 Rallye model. If it is the frame is TreTubi Columbus wif Alle stays. The catalog shows Campagnolo; Grand Sport headset, pedals, front der, crank
with 'sport touring triple', Record seatpost (catalog shows fluted), Tipo hubs wif Record skewers, and Rallye RD! Mafac cantilevers, Mavic rims. Nice package.
OK. The catalog doesn't show the chromed crown but since the two bikes below it had it and the three above all have it this could have simply be to steamline production. The chromed chainstay and dropouts is in line with the catalog. The color of the decals is off but that could have been a production change or later replacement (which might explain the Specialissma decal).
I think you need to try for the whole bike, especially if it still has the Campagnolo triple, although it's a faux triple with all three rings in the same BCD, and Rallye RD.
If you can't buy it whole the frame is a great deal IMHO. Get lots of nice pics for @
T-Mar serial number thread too!
