Bike for turbo trainer

Ive just purchased my new tri bike a Quintanaroo Seduza and love it, the only issue is its Autumn here in the Uk and getting damp and cold, so was thinking of buying a turbo trainer for the winter so that I can make the most of the £ spent on the new bike next race season, my question is will I do any damage to the Seduza using it on a trainer or do people have an old bike for there turbo trainers, any advice welcome.
