Regarding with 1R's with an alloy quill bolt -
I have one as well, new logo, pantographed "Cinelli" on the right, "C" on the left. It surprised me to see that quill bolt and expander were both alloy when I received it. I would not bet my life on it either! I figured it was aftermarket "upgrade", depending how one defines upgrade...
Could be that one could install the stem using a conventional steel bolt, ex pecting that the alloy expander will get itself wedged, then repla ce the steel bolt with the alloy bolt... and then hang the bike on the wall and just look at it while smiling about the 30 gram weight reduction...
