    Has anyone any experience of using a carbon frame bike on a turbo trainer? does it do the bike any damage?

    How could it do any damage?

    It wouldn't bother me, but if you're paranoid check with the manufacturer.

    When I got my turbo trainer I worried about the same thing. I did ask around quite a bit before buying and everyone I asked said not to worry.

    My bike has titanium inserts in the fork and the rear dropouts which look weak. I was pretty worried about the rear dropouts and how they would handle the stress as the bike is clamped at these points. I used the bike on the trainer quite a bit during the winter with no problems at all.

    I still wouldn't go off on a mad out of the saddle sprint but for regular cycling on the turbo I really wouldn't worry about it.

    The frame is held at a single fixed point and noticeably flexes around that point, which means that the stresses on the frame are significantly different than seen on the road. So it is a perfectly reasonable question.

    OP, loads of people do this, with no issues. Although it takes a while before you don't think about it.

    I have heard it's a bit of a no-no. If you have the luxury of an alloy training hack I would use that.

    dunno why yet, but I couldn't change my front derailleur on my carbon bike in the turbo during the week for some reason. worked fine when I took it out. can't explain it, can anyone else?

    I found this too, the bike would change to the big ring no problem out on the road but on the turbo it would struggle a bit. I wouldn't have thought it'd be only a problem for Carbon frame bike though.

    I was thinking the reason must be that the vibration of the road must make it easier for the chain to get a purchase on the big ring by making the chain move about a bit. Whereas on the trainer your only relying on the derailleur cage to push the chain over until a tooth catches the chain, I think vibration from the road must help this happen more easily.

    I put a bit more tension on the front derailleur cable for the turbo session and it was fine.

    Thanks for those replies folks. Had contacted manufacturer but no word back yet hence my posting. Will probably risk it later on in the year anyway. Thanks again.
