Carbon frames on turbo trainers, can it cause damage?

Postby p1tse » Mon Jan 28, 2013 20:04 pm

Putting carbon frame bike on turbo trainer can it cause damage from the pressure being held and then if pushing hard out of saddle training make things worst?

I have no idea but from what im told it voids warranty on almost all bikes and when I asked how would they know I was told that stress cracks around the crank area are a dead giveaway.

Carbon frames are fine. Just don't do any daft out of the saddle stuff (regardless of frame material).
More problems but still living....

I do not doubt that the manufacturers state it voids the warranty, but that fact in itself does not actually prove that the turbo would adversely affect a carbon frame.

I tend to work on the common sense principle, and for me I see nothing going on via a turbo that does not go on when road riding (yes I know the rear wheel is clamped in).

I use my carbon bike on the turbo and if it does fail then I guess we will have some evidence - until then I intend to use it however I see fit.

I wasnt telling you off for using your bike on the trainer, simply saying what I had been told and how the manufacturer will see it if it fails.

I did not think you were :)

I am quite happy to be wrong too, but for me once I have reasoned something through I go with my deductions and live with the consequences (mind you I have been divorced twice) :shock:

I asked as I was ******* through manual and noticed a note about carbon frames shouldn't be used in trainers, which didn't surprise me but made me think about it

Thanks so if used sensibly should be fine

I only have the one road bike and it's carbon, so it has to go on the trainer. Make a point of minimizing lateral movement and focussing on keeping upper body as still as possible and pedalling smoothly. It'll do wonders for your time trialling.

Errhhh... so putting a carbon bike on a turbo causes more stress to the frame than say hitting a deep pothole at 40mph?

Let's hope not, eh. I think the point being made was that the frame experiences significantly more stress out on a road ride than it ever would on a turbo.

- or a dead giveaway of a strong pedaller, or just a lot of use - or a faulty frame! I think they'd have a tough time proving the cause of cracks in that highly-stressed area when they're in front of the small claims court for not honouring a warranty.

I didnt intend my comments to be argumentative, just passing on what I was told.
I personally wouldnt do it although I am soooooo tempted as I just want to ride the thing so ive stuck with the bmx on the trainer for the minute and will simply buy a cheaper road bike for the trainer when I find one at the right money.
