Anthony, I believe someone changed out your binder bolt (handlebar, not the stem bolt right?). There were aftermarket alloy bolt kits back in the mid-1970s for changing out the steel bolts for lightness.

Cinelli did use a aluminum stem bolt (not binder) later on some of the Cinelli 1R stems 1978 to late 1980s

Here's the definitive Cinelli Timeline on Jack Bissell's http://www. 43bikes.com web site: http://www.43bikes.com/cinelli-bars-stems.html

Anthony, Chuck, Jack, everyone,

Chuck's message above indicates that some 1-R's had alloy stem biders (the big bolt that tightens the stem into the steerer). Jack's timeline indicates some (not all) were alloy. In my experience ALL 1-R stem binders were alloy. Has anyone seen a 1-R, NOS, that has a steel binder? Chuck's post suggests that pre-1978 they were all steel, but the only old-logo 1-R I own came to me still in the package and it had the alloy bolt. I'm certainly open to the idea that some were shipped with the steel bolt, but I'd like to know if anyone has seen one that way in the original packaging. I think a lot may have been switched to steel by apprehenive users.

For what it's worth, the alloy Cinelli bolt is larger in diamter than the steel one. I think the alloy is 8mm x 1.0mm, while the steel is 7mm x 1.0mm. The alloy is still quite a bit lighter, despite the bigger cross section.
