Colnago Super rosso Saronni 1979

Maybe you're right... I'm not so expert in Colnago timeline models...
But according to various examples that I've found on the web this bike should be a '79 maybe '80 model...the problem is that there isn't a serial number stamped on the frame or some kind of detail that shows something useful (maybe I can't recognize it).
The only thing that helped me was the fork: it's a flat squared head one...later '80 models have a more rounded "aero" fork...(ehm..sorry for my awful terms :-D )
What do you think??
Thanks in advance.

Thank you very much!
I agree with you...This is my favourite Colnago color scheme too and i've been very lucky to find the original factory color scheme used in those days...

Thanks for your advice...
Actually I've tried something very similar to what you have suggested...I poured a lot of penetrating oil from the bottom bracket and waited 3 days... but when i've tried to turn the saddle i've been afraid to damage the frame...believe me, I put a lot of strenght but the seatpost didn't turn and the frame started to bend too much so I gave up...i think the only chance left is to cut it like suggested in the Sheldon Brown site...
sob!

Maybe you will have to cut but I would keep at the penetrating oil. Do another round of it just like you did from the bottom bracket (try the liquid wrench brand oil). Let it set for day upside down. Then flip it back over the next day and attach an old crap saddle. The next part some people may disagree with but has worked for mew everytime. Get a rubber headed mallet (mole whacker style) and pound the nose of the saddle. I usually do 3 smacks from the left and three from the right, until I see the post turning. Then I grab it by hand and turn it hard back and forth until freed. Every frame I have done it with can take it, the seatpost junction is pretty strong on a bike.

Put a little penetrating oil on the top side too around the lip. It helps. Don't forget to loosen the seat post bolt all the way out, again it seems to help. Lastly once the seatpost is out make sure to clean it off with some steel wool and a little smearing of oil. Good luck! Nice bike!
