Aero Bar Shim For Quick Release Handlebar Mount

Does the job of keeping the light securely attached to the handlebars. Some might argue that it's expensive for what it is, or that it should be included with the light as standard now that flat topped bars are more common. However, as the alternative is a less secure fit, it ser es its purpose well.

Fits perfectly on my flat handlebar. But, I use Aero Silicone Band, because it fits better on a wide handlebar.

Works perfectly with aero handlebars.
