I asked the same question a while back and the general response was there should be no problem

Im 230lbs and using my carbon Kuota Kharma on my kurt kinetic without any problems...

[reply]I am close to purchasing a 1upUSA trainer and was wondering if I should be concerned w/ using my carbon frame with this trainer or any other trainer.

Thx!![/reply]

No worries.......
