The first impression is satisfied and also on the handlebars of Tourrades the clamp holds the camera in place - only on the track (not the hard way, rather than curbs) the holder is unfortunately the shaky candidates. A small screw makes the connection between ball joint and clamp. Where the union nut keeps everything nice and firm breaks into the plastic bolted 4mm screw simply, or is only loosened times.
Too bad, compared to the much more expensive mounts actually a solid part, we will try to stick to the transition and thus to fix, then it might work.
