Thx for your reply, the reason I guessed it was 80is because of the small tube between the chain stays is still a tube. According to some timeline tables from 81 the chain stay bridge had more like a spool shape + colnago stamped on the sides of chain stay..
But again not an expert, just what I found on the internet from my own research.
I will try to take some more pictures of the clean bike tonight.
The pics I made in album is when I just got the bike (very dirty)
Anyone has an idea about the number 'H36' on the bottom bracket? -- as I think it has not been replaced, but could be wrong also.
I'd like to change my build date estimation to 1980 as I've had a closer look at the frame photos. All indications that date the frame seem to point to 1980. As for the stamping under the Bottom Bracket - it was a common belief that the stampings were undecipherable but now (I think) some guys can interpret these marks.
Why 1980:
- conical seat stay caps
- straight seat stays
- recessed brake bolt heads
- straight rear fork bridge
