Some bikes don't have round bars and our Phone Mount with USB Charging
Port needs to mount to a round bar. Here is a solution. This extension
mounts under the mirror stem on "most" bikes using handlebar-mounted
mirrors. The diameter of the hole in the mount is 10mm. Unscrew your
mirror, position the mount at the base of the mirror mount then screw your
mirror back onto the mount.
BEFORE ORDERING PLEASE CHECK THAT THE
DIAMETER OF YOUR THREAD AT THE END OF YOUR MIRROR IS 10MM
