Going from 7/8” to żone inch?



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?
