now that's a wild ride, indeed! But '84? I'd think that early would be even more rare, my guess is it has to be just a bit later.
For example I have a fork with that same crown and it's marked Ciöcc but AFAIK that fork is from late '80s.
And I think the "spoiler" Cinelli BB shell as well as the Columbus tubing decal (SLX?) with red border were from '85 at the earliest, but could be wrong...
