How to tell the manufacturing date of Colnago from the 70's to the 80's

Permalink  
 

Colnago Super from the early 70's to the 80's look quite similar

Unfortunely, the serial no. doesn't tell the time/ date that they manufacture

Any expert here like to shed some light here?

c. Rear derailleur cable guide braze-on at bottom of chainstay
d. Long Campagnolo rear drop out


On the fork,
a. Clover cut out on top fork crown
b. Two holes drill at side of fork crown
c. No cut outs or holes drill on fork tangs

Colnago Super 1972-1973
You will find:

On the frame,

b. Rear derailleur cable guide braze-on on top of chainstay
c. Long Campagnolo drop out

Colnago Super 1976 onwards

Please note that the frame share the same serial no. as the fork
You can locate the frame no. at the rear dropout
And the fork serial no. is at the steerer
At later years, no more serial no. on the fork

Imo, Colnago build frames of the best quality before 1975, and after the "Colnago Master" were introduce
Their quality when down because of the bike boom period.

Please let me know if I'm wrong or to add details

 In addition to KJPoon's excellent information, there is some pretty good info to be found via Google. Wikipedia has a decent page. The CR list has a lot of experts who can tell you more than you ever wanted to know.

 

And if everything else fails, you can always email the factory with your serial number. But do this last. In my case, I have a very rare steel cyclocross bike that does not have a serial number, and as a result, the factory could not give me any information. It was one of two bikes built as "favors" for riders. The first, in the mid '70s, went to Roger de Vlaeminck.

Mine was built in the mid '90s. Colnago lugwork, extended wheelbase, "Masters" logo on brake bridge. Unicrown fork. Very sweet. Unfortunately, it has no serial number, so the factory could/would give me any information on it. 

I have not been able to find any information about this bike online anywhere. Equipment pictured as built was not the original.

Further to KJPoon's list of historical changes to the Colnago Super, I would like to share this link to those who would like to actually see images of frames from these years at http://www.cycling-obsession.com/how-to-indentify-a-colnago-super/

If you would like to see photo's of other frames Colnago manufactured from 1968 to late 1980's, then refer to this link http://www.cycling-obsession.com/how-to-identify-a-colnago-vintage-bike/

Of course some may consider these bikes 'classic' rather than vintage, so please excuse the terminology, it's still a great article smile
