Hi Rise Bars on a vintage Trek 950 Needs shims.
Bought 25” x 13.5” x 7/8” handlebars so I can sit upright as I ride. Didn’t check the stem diameter.
I had some galvanized steel handy so I made shims.
Might have to slip in one more small shim, it’s almost tight enough.
I checked Google and there are commercially available handlebars shims, do you think they’re worth the $8.59?
This takes shade tree mechanic to another level. I would really want to be sure that the edges of your shims were not able to score the handlebars as this would be a serious stress riser leading to failure of the bars (assuming they are aluminum).
