I have a Trek Fluid 2 (Cyclops) trainer.My question is this: Will/Can the frame flex and have different stress points from riding the bike while it's on the trainer compared to normal road riding? Is there a risk to twisting the frame, or even the crank for heavy riding on the trainer? I have an aluminum frame (Trek 7500fx), and I weigh around 230lbs. Thanx in advance.

I have this same trainer, and weigh 280 pounds (when I got it, I weighed 330). I have an aluminum frame also (Lemond Tourmalet), and I can see the BB flexing around down there, but It's never given me any trouble.
I used to use a steel framed-diamondback in there, and it would flex so much, it'd change gears all by itself.
The trainer supports the bike by the rear skewer, so I'd expect that to bend before the frame.
