Just fished this thread up whilst searching for '89 Pinarello catalogues on google. Does anyone know how to tell a '89 Treviso frame apart from an '89 Asolo? I can't find any different features apart from the decals, but mine has no decals, just the signatures etc.
I've narrowed the frame down to these 2 models but I now want to get it restored so I need to find out the original colour scheme and correct decals to buy.
My frame has a bridge on the chainstays near the bb with cutouts. It has the correct fork crown for this period. External cable routing. BB shell has PINARELLO - TREVISO ITALY on it with a small cut-out. Chrome is in the correct places. I'm 99% sure it's an '89 Treviso or Asolo but not sure which one.
Could seatpost diameter tell me? Surely Columbus SL & Cro-Mo would take different seatpost diameters right?
EDIT: I just checked sheldon's database and it says SL would be 27.2 and Cro-mo 27.0 - this should give me the answer shouldn't it?
