OK, I suppose the first comment is that they are all odd-sized ...

Anyway, here's what I have: what seem to be "vintage" Cinelli Campione del Mondo 66 handlebars.

I tried to get a closer picture of the logos, but could not get anything in focus. To describe them, the logo on the bike's right side is a knight in armor partially covered by a shield bearing the words "Cinelli" and "Milano." The logo on the left side of the bike are the words "Mod. Campione del Mondo" surrounded by winner's laurels (wreath-like boughs) tied together at the bottom.

I have no way of confirming the age exactly, but they were pulled from the thrift shop find described at:

Based on the steel Campagnolo sport crankset on the bike and other factors, I believe this bike to date to the early 70s. I assume - but of course don't know - that the bar would date to the same period. The stem on the bike - also Cinelli - uses the small oval "Cinelli - Milano" logo, if that's any help.

Here's my conundrum:

The bar clamp area measures 26.0 mm (or perhaps even 25.9 mm). I thought that pre-1998 Cinelli bars used a 26.4 mm clamp diameter.

Also, the width of the bar seems to be about 41 CM, center to center. Given that the bar is (was?) made in 40, 42 and 44 cm widths, this does not compute. To my untrained eye, there's no indication that the bar has been bent. To confirm this latter point, I have taken some measurements (such as bar ends to center of clamp area), which suggest no unusual bends.

I saw one fellow on the web (from the Netherlands) who indicated that he has "410 mm" Campione del Mondo 66 bars (on a Dutch "Union" bike from the 1970s), but it's the only reference that I have seen to this width.

Any ideas or observations would be appreciated. Thanks.

Just to screw with us:
Cinelli measures bars outside to outside, not c-c. And they measure their stem's reach perpendicular to the quill, not along the top.

But the 26.0 instead of 26.4, I'm no help.

Interesting. Thanks, Ex Pres, for this information.

For some reason, I thought it was a c-to-c measurement. I am at work right now and don't have the bar with me, so I will need to re-measure the width this evening.

Also, your comment regarding the measurement of the throw of Cinelli stems makes a lot of sense. I measured the stem from this bike using the "conventional" method last night and it resulted in 105 mm, which seemed odd. I will re-measure it this evening as well.

Most Cinelli bars I've seen have the size stamped on it. 66-42 would be a model 66 (Campione del Mondo) in width 42 cm, however it's measured. That may not be true of your bars, which appear to have an “old logo.“ Try VeloBase.com. Maybe your caliper's off, or maybe they were made for another market than the usual 26.4 center section.

Thanks for the suggestion regarding VeloBase.com. I will check it out.

This particular bar is stamped with "66" (only) in one location only: on the outside of the right-hand bar end.

I had the same thought regarding my caliper, which is both cheap and old. I should "truth" it by measuring some other items with known dimensions.
