This bar clamp is designed for high impact off road, motorcycle, and aggressive mountain bike riding. The clamp itself can be adapted to fit 7/8", 1" and 1.25" bars, using the supplied bushings. Compatible with other 1"/25mm industry-standard ball systems.
I have two mounts in our R44 Raven II Newscopter. One holds my phone and the other mounts my MS Surface Pro 3. Both hold them rock solid especially in a high vibration environment.Really nice quality!
The mount was easy to secure and holds on to my handlebar with reassuring stubbornness. It doesn't slide or rotate out of place, even when burdened by a plus-sized phone and/or subjected to bumpy roads and fumbling hands. The quality shows.
