Velo-Retro: Cinelli Timeline
"Every Cinelli stem had a 26.4mm clamp all the way until the 1990s, with a freakish 26.0 exception from the '60s."
So if they made some 26.0 stems, it seems reasonable to think they also made some 26.0 handlebars?
Yes, there were 26.0 "early" Cinelli bars. I have had two, mine were without anodizing. The VAST majority of the "crest" bars are 26.4. But, test, don't guess.
Some claim the knurling for the stem provides identification, measure.
