Trainer damage?

Is there any validity to the idea of a bike being damaged when used on a stationary trainer? I have
read several posts on other sites that suggest this possibility and since I have recently started to
use one, I am a little nervous about any damage I could be causing to my bike.

I only ride seated which seems to keep the bike pretty straight while on the trainer. A friend
of mine gets out of the saddle and really puts in a big effort on his and I wonder if that is a
good thing?

Thanks for any advice or opinions.

We touched on this subject a while ago here. I recall a roller manufacturer casting aspersions (
without an actual accusation which would have needed some backup) on trainers offhandedly in an ad,
something like,"Won't twist your frame as trainers may" or some such.

Having sold literally a couple of thousand of the old style trainers (into which one clamps the bike
by the fork and behind the BB) and even more ofthe modern ones ( which support the bicycle across
the rear axle) I have never seen a case of frame damage from a trainer.

Consider for a moment that even a careful rider subjects the bike to a magnitude more impact on any
Sunday morning than a trainer ever could. I can't see how a trainer could be a problem for a
bicycle frame.

OK, maybe except for possibly clamping the old style clamp on the chainstays until you crimp them -
but it would take real work to do that.

Thanks. I know personally it does not seem that any harm is being done to my bike while I'm on the
trainer. I must have seen a similar ad that stated that trainers are great but...

The special front-wheel QR skewer that came with my Tacx trainer bent pretty good while I was using
the trainer. I had both the skewer and the stand screwed in pretty tight, so I'm not sure what
happened. I noticed it when I was putting the regular skewer back in. Does this harm the wheel?

I've noticed that some score up the ends of the rear skewer. :-(

I don't see how it can damage the wheel. But a skewer that's bent reflects likley having been
installed not-quite-tight-enough or perhaps askew (maybe on top of a Saf-Tee lip??).

Add a drop of oil on the cam and the threads and ensure you're locking it just as you would any
other skewer - hard enough to see the print of the lever on your palm for a few seconds ( but less
than a purple mark!).

The wheel's surely OK but I would look at the fork tips if the skewer slipped in use. Are they
parallel? That is a concern, but still much less serious than a loose skewer out of the saddle
in traffic!
