Most of the Loctite varities (609, 648, 680) that would be good for this are the wrong viscosity...they won't flow into the gap, unless you could come up with a way to get some pressure behind them (then they'd be great). Loctite 290 will flow into the gap, but I don't think it'd be as good as a thin superglue.

Franciscan Hobbies (on Ocean) carries a good range of cyanoacrylate adhesives (Bob Smith brand, if I recall correctly), including one with very water-like viscosity that should do the trick. I think you'll want the one called Insta-Flex. They also sell fast-curing catalysts that will prevent the white finish that sometimes happens when superglues dry in air, and some Un-cure stuff to remove excess. That would be my next stab, possibly with a couple of rivets on the underside, near the stem clamp (but make sure the gap in your glamp is such that you can get the bars in and out with this fastener's head sticking up there.

Good luck.

To be clear, the slipping is not occuring between stem and bar, but between the bar sleeve (with the stamped Cinelli logo) and the actual bar.

Unheard of, maybe. But these bars are probably some of the cheapest bars Cinelli ever made - the upright bars that are rumored to have been installed on the Pope's Colnago. While they are cheap, they are very rare and quite comfortable.

There is a very thin gap between the sleeve and the bar caused by a slightly curving bar and a completely straight sleeve.

Can anyone suggest a glue that is like water that will penetrate the thin gap? I know it sounds like a rig-fix, but superglue????
