Carbon Seatpost on a Steel Frame?

To clarify on the failure modes.
I was referring to cyclic loading within design parameters. Yes AL is sensitive to this too. Within parameters, the carbon part will not have an appreciable service life limit, assuming no delamination.
If the parameters are exceded, or suspected to be exceded, it should be tested. The reputable makers reccomend that you do send them in if you suspect the part. Beats a lawsuit.
Cool on the nanotech.

Thanks for the clarification. I love it how the makers of high end aluminum seatposts recomend that you just throw them away and replace them after every season of riding.
