Nice bike. I agree with the comments from Scooper and Pastorbob and can add the following. The fork crown cutout and seat stay attachment suggests the 84-86 range. A couple of details suggest things unique to 1984 and those are - Cinelli BB shell (my 84 has one, my 86 does not), if I see the picture clearly, it has cable guides on the top of the BB shell (I think only on the 84), and the derailleur cable stop is on the top of the chain stay. I think Pastorbob has an 84, does yours have these details?? As previously suggested, if it is an 84, it came with the rare rainbow decals. In any case - you have a nice one, enjoy!
