Updated: 04/17/2021

- "Super" decal on chain stay

- "Eddy Merckx" style fork crown used in very rare instances
- "Playing card" club decal graphics. The Colnago Ace of Clubs logo was inspired by 1970 Milano-Sanremo victory in March by Michele Dancelli. Sanremo is The City of Flowers and the Ace of Clubs is known as the Ace of Flowers in Italy. Note that before Milano-Sanremo the club-shaped lug cutout was not a Colnago logo but only a club-shaped lug cutout. Using one of the four card suits, Clubs, Diamonds, Hearts or Spades for the lug cutouts was common with Italian frame builders.

Year dates are approximate; changes might have occurred the end of one year or the beginning of the next for example. Paint schemes, panels, decals and chrome varied according to how importers spec'd their frames, so this all varied considerably and there are anomalies. Dates and details based on the Classic Rendezvous archives, the Wool Jersey Gallery, and Colnago and Bikcology catalogs.

Serial numbering only started for Colnago on USA-bound bikes when the CPSC started requiring tracking, etc. West Coast Cycles was importing Colnago at the time and the serial numbers started for their product. There is still no way to determine manufacturing date by the numbers, except that they are 1979 or later....

I would greatly appreciate any assistance you the reader can offer in updating this timeline as this is the only way the accuracy of this timeline can be improved. Chuck Schmidt
