It depends on where you're intending to mount the camera as it's going to be a 
very exotic bike that doesn't have at least one round tube somewhere.

You do need to be careful about how tight you clamp things on carbon, but that 
applies to aluminium as well.  Non-round shapes are definitely going to be much 
more sensitive.

I recently bought a couple of these for my tail light, which might give you 
some ideas.

Here's the whole category:

My light came with the flex-tight bracket but it's sized for larger diameter 
tubes and the light doesn't fit well on the seat tube, hence the seat stay 
mount.

Combined with some clever dremel work you might be able to use something like 
that if it's strong enough.

Whatever you do, I'd strongly recommend cutting a piece from an old inner tube 
and wrapping it around the frame to protect it from scratches.  You only need a 
small piece to fit under a clamp and the rubber grips pretty well.

I think for irregular shapes your best bet might be zip-ties.  It's very common 
to use them to mount bike computer accessories in places that aren't 
necessarily designed to be clamped (forks, chain stays, down tubes).

I'd volunteer for testing but it's not entirely practical... unless you felt 
like some better weather right now!

Cheers,
Dave
