Drift Innovation Rollbar Mount. Get out on track and shoot a smooth Full HD video with this one. The Rollbar Mount’s adjustable grip attaches your camera to bars between 36 mm (1.4″) and 63 mm (2.5″) in diameters, such as on a roll-cage, go-kart, or bike frame. The Rollbar Mount can pivot 180°, and rotate 360° with your camera, so you can capture all the overtakes, apexes, and wheel-to-wheel action from practically any angle. Made from super-tough nylon, and with a new ratchet washer system, the Drift Rollbar Mount securely locks your high-definition cam in place for all the racing action.
