Shims work better than tape!

replaced the handlebars on my new ebike and needed this shim to make it fit.

Have to nudge them a bit to make symmetrical, but not that difficult.

Great quality but says it fits 31.8 but I found it was just a bit on the small side for this size. It was loose in the stem with all the bolts tight.

Works well and as intended. Fit just right but it warped for some reason after a few months.

Thank you so much

I needed to do a little customizing of my new bike and I found I had to shim the handlebars. These were perfect for the job and easy to use. I would highly recommend.

These work great on an older bike with smaller diameter old school handlebars and allow me to use a newer stem. No slipping at all. A bit tricky to install by myself but they are on now and doing what I hoped they would
