You got that right! Maybe they bent the bars to shape from straight stock after passing through the stem?

Micrometer says about 24.7mm inside diameter. How do I know? Because...

Upon reflection, I decided that's correct. So, to possibly save the stem, I hacksawed the bars to release the stem. So, my WTB 1.0 is to find bars to fit, my WTB 2.0 would be bars and a stem. Unsure what bars fit a 24.7mm hole.

The more layers between the bar and stem, the greater the chance of slippage.
Presuming I found some 23.8's, to fit a 24.7mm stem means 0.45mm shim. AM i calculating that right at 17.72 1000th's of an inch thick? Less any desired clearance, if indeed any is desired (I'm going through a "clearance crisis" on a seat post now at the same time).
