I wouldn't clamp the stand to it. Get a cheap heavy metal one the same = size and use that. Sure,
it's a hassle, but if you break the post, you = may also have a hard time getting it out. And if
your frame is as high = tech as the seatpost, you may end on damaging the frame trying to get =
the post out.

Use a seatpost with a big seat rail guide, not a BMX style post. Cause = the post could slip out the
bottom of the clamp and more $$'s go flying = away :-)

The amount of leverage on the post will not be a problem - after all you will have less leverage on
the post than if you were sitting on it.

The thing to avoid is crushing the post, and whether that is a risk depends on the clamp design and
how you use it.

I think it's generally safest to avoid clamping carbon posts and instead keep a 27.2 cheap steel
seatpost for the purpose of clamping bikes (or frames) that have a carbon post or no seatpost.

If the clamp isn't adequately padded to protect the post, then don't clamp to that post. Remember,
the post is strong enough to support *you*, with all the bouncing around that you do. The bike, by
comparison, weighs a lot less. On the other hand, if the clamp is poorly designed or made, and
crushes or badly dings the post, you may induce a failure where none would have been. I agree with
the recommendation to acquire a cheap aluminum post of the same diameter for use when working on the
bike if you're at all concerned about damaging the carbon component.
