Hello there. Your bike should be from '88, that's what the first number says, I think Alfredo will tell you the same. The difference between Compact and Compact Pro, aside from tubing is minimal. The only noticeable difference is in the seat cluster. Compacts where built from Columbus SL, SLX, Oria Ranf and (get this) Vitus GTi. Compact Pro is built from custom Dedacciai tubing most likely based on SAT 14.5 (my speculation).
Gios was sold as frameset although you could order it as a complete bike (a previous owner of my bike did just that, see the pics attached).
This is the first time I see Gios in that shade of blue and I think it looks spectacular, congrats.
Question for luker. Do you have the 40th anniversay transfers in digital form ? I'd like to get the original stickers back on my bike, previous owner chose to redecal it with newer logos.
