Carbon Frame Vs. Cycle Rack

[G-Zero]

I have previously read on CC that carbon frames shouldn't be clamped in workshop stands etc, but what are opinions on a carbon frame bike being carried on a bike rack, where all the weight is carried on the wheels.
The frame or seat post is held in place by a rubberised ratchet strap system, without applying any real pressure to the frame or seat post, and further rubberised ratchet straps hold the wheels in place.
I can add pipe lagging or similar to help protect the surfaces where the straps touch, but I can't think of any reason that the bike couldn't be carried safely and without putting undue strain on the frame, unless I'm missing the obvious ??

Should be fine. The only time I have changed stuff is not clamp deep section carbon wheels, the ones I had for racing we're Hed Jets which are non structural carbon, so left standard wheels on for transporting.

So long as you don't over tighten, fine. Same with any material.

Seatposts tend to be much thicker and can be clamped firmly. I clamp my carbon frame in my workstand by the seatpost, no problems. If you don't need to clamp the frame in your carrier just strap it firmly, it should be fine. I assume yours is one of the drop down types you get on campervans.

Thanks to you both.

H71 - Yes, it's the drop down type (Fiamma)

If the seat post is strong enough to withstand enough pressure from the clamp not to slip down with a rider sitting on it, I reckon that it'll be strong enough to withstand the sort of pressure you could exert with a rubber strap like that.

We put my mates Scott CR1 Pro on my Thule 591 Proride without any problems

Never had an issue myself

That makes a lot of sense
