Solid fit for my handlebars
I needed a shim for my bike since I was upgrading the handlebars. This Autohaux shim worked perfectly, reducing the size from 31.8mm to fit my 25.4mm stem without any issues. Installation was straightforward, and it feels sturdy while riding.

Not what I expected
I was a bit let down when I received these. The color seemed different in person, more dull than I thought. They still work as intended, but I was hoping for a brighter appearance to match my bike.

Decent but had a hiccup
The shims fit well, and they seem to be made from good material. However, the shipping took longer than expected, which was a bit annoying. Once it arrived, though, they did the job well and I’m happy with my bike upgrades.
