This new dual handlebar mounting attachment has been designed to fit onto various width bars between 20-33mm.
There are 2 mounting points, First is the 3 Prong Ultimateaddons quick release adapter system suitable for mounting your UA case or holder. Second is on the opposite side, there is a connection suitable for mounting your action camera with your own supplied clip. Please note that the clip is not provided but is normally supplied with majority of action cameras including GoPro systems.
This is certainly a mount with a difference, keeping your 2 favourite devices mounted in one place!
