Does anyone use their Calfee regularly on an indoor trainer, like a Cycleops fluid trainer or along those lines? I had read somewhere that mounting certain carbon frames on a trainer and really hammering it(out-of-the-saddle sprints, or big gear mashing) during indoor training sessions can cause breakage - but I've never seen or heard of this actually happening. Is this true? Has anyone ever had problems with their Calfee on a trainer? Winter is just around the corner and I just got a fluid trainer.....not sure if I should just mount the steel steed on the trainer for those indoor sessions and leave the carbon for outdoor rides.

Unless Calfee was told that it would be used on a trainer (and therefore strengthened the frame accordingly), I would not put it on a trainer. Rollers are ok, but trainers put forces on bikes that they were not designed to take. Put a beater bike on your trainer.

I've used my Luna on a trainer M-F during the summer and winter for about 2 years now. I had never heard or read that special considerations should be taken for such a setup at the frame level, though I guess perhaps it should.
I am no physics expert, but I would think the forces applied by a trainer are pretty similar to the open road as long as the bike is properly secured in the trainer and supported. Trainers do secure the rear wheel, so maybe there are "unnatural forces" on the rear triangle? I don't own a "beater bike" to use solely in the trainer, but if this is a major concern, perhaps I should look into getting one.
Maybe we can get Craig's official opinion on the subject.

Exactly. It is the fact that the rear wheel is secured. When you stand up and crank on it, you're putting side to side forces on the frame with the wheel fixed. This never happends on the road.
If you don't do that or if you are fairly small, you may not do any harm.

I would not put any bike that I cared about on a trainer.It is senseless stress/flex cycles,sweat on paint, and if you want to ride out side you must remove it and then reinstall it.
You can get a beater frame for close to nothing and not worry about it.Also,I use a 55x11 on the trainer for "weight" work outs,with an 11x23 cassette. I can get exactly the resistance I want and the bike is always ready.
Show your Calfee some love.
