Interesting design. the 4 part clamp thing for each base bar is smart. Idk if i'm man enough to try it, it would bum me out so bad to crack my cockpit and have to re-hose & re-bleed my brakes
I'd probably use electrical tape on the clamping surface to even out the clamping force, because there's a good chance the angles / curves / interfaces won't really match.
The biggest bummer of this is the absence of tilt. Nobody's running horizontal skis anymore. Would be worth asking if they have a spacer with a 15 degree angle or something like that. Most of these bars mounted on non tubes, to go from horizontal to angled, use a spacer with a slope.
