Bits and bobs... the fork crown panto is more of a Colnago C thans Cerliani's simler sans serif font.

The bike is interesting but has suffered an impact .
the blue frame set is much less intriguing and a good deal smaller.

no idea as to the best size

seatpost on the bike is way way too high.

the crankset is record (c-record)... see the hidden 5th chainring bolt. first generation chorus has all 5 showing. that makes the headset likely c-record as well. I am not sure there was a c-record and a chorus headset... they might be the same part number. both from late 80's time frame
