I replaced the bar on my Trek 7.0. However the new aluminum bar is a bit narrower, and some older Performance extension-bar add-ons I have will no longer clamp down tight on this bar! The bar measures about 2.1mm dia, but so do the extension clamps, giving me no room to tighten them!
So, does anyone know where I can get two handlebar shims (about 1" wide ea) to increase the bar's fatness? Tape wouldn't be strong enough, I need something in metal or very tough plastic I think.
