I have a CONTOUR Roam mounted to the bars using a RAM 6" double socket arm, a 1" ball mount on the bars and a 1" ball screwed into the bottom of the camera. I can easily reach up and turn the camera ON or OFF even while wearing gloves, and I can SEE when the camera is ON or OFF. I can easily adjust the camera or remove it and the arm with a twist of the arm knob.
