I've been using a Manfroto Professional series 2900 Super Clamp on my bike in various locations on the frame to mount a camera. It's by far the most secure mount I've ever seen, and I believe it's designed to hold lighting equipment weighing a lot more than any bike camera. Anyone else try this?
When it's on there, it goes NOWHERE. Easy to remove the clamp or the camera, and the stud is standard for all camera and lighting material.
