you'd think that 1mm or 0.040" shim stock would do the trick

well i'm not adverse to shimming either, just simpler i figured to grind the space down and let the bolt cinch it a bit more, looks like there is enough material there to handle it.

If you grind enough to close up 2 mm then the clamp will become oval shaped and lose contact area. Use a shim. I like aluminum, but have used mild steel.

i would be worried with a shim that the might slip when you have to much pressue on them. sell them on ebay and buy another par.

I have shimmed clip-ons on race bikes before. They even crash pretty well.

i'll shim them, you just cut down aluminum sheets or is there some sort of specialty shim product? my boss told me about a brass shim, something called onion brass, anyone familiar with that?

onion brass? hmmm...never heard it called that before. go on the mcmaster carr site and do a search for laminated shim. basically a bunch of .001" or .002" thick sheets that are glued and pressed. you peel them apart...like an onion.
