Looking for a handlebar shim. 22.2 -> 25.4mm and approx 50mm/2" in width. Ones I've found online are either two short or too long in length. Preferrably anodized black.
Problem Solvers make shims like you need. But their 22.2-25.4 mm ones are narrower than all of their other ones. :?
I'd probably buy 2 sets, cut some off of each, and use 2 pairs cut down with the cut in the middle where it would be hidden. They're aluminum, so would be easy to cut.
