URBAN Mirror Mount
The URBAN Mirror Stem Mounting Bracket works on any mirror stem or other round bar measuring 3/8 inch (9.5mm) to 1/2 inch (12.7mm). It can be mounted in any direction ('front' or 'back', 'left' or 'right').
We call this the “Stealth Mount” because it's so unobtrusive; the bracket measures less than 2 inches square! Plus, the location on the mirror stem is out of the way of anything and everything.
