I have both and in the winter I do spend a lot of time on the trainer. Is it better to ride the road bike on the trainer or the tri bike. I personally find the road bike nice to ride on the trainer but is it a good idea to use the tri bike and get use to the positioning. I do ride outside once or twice a week on the road bike but ride the trainer 3 more times during the week.
Honestly, I ride both. I have a 2002 Trek 5200 and a built 2003 Trek TT. I noticed that the road bike sways a little more in the trainer. Plus, I have DA10spd on my TT, which is way better and smoother shifting than the 9spd Ultegra/DA components on the road bike. I like to ride both because I can do longer rides on the trainer on the TT and still keep the flexibility of the aero position. Hill climbing can be done on the road bike. Hopes this helps.
i haven’t ridden my tri bike since last november or so. strictly road bike on the trainer for me. my tri bike is a lot more expensive than my road bike, so i don’t really like the idea of clamping a trainer onto it or riding it outside in the winter (they use salt to de-ice the roads where i live). would the trainer damage the bike at all? i doubt it, but i just prefer the less aggressive position of my road bike for those long trainer rides. i find getting back on the tri bike a couple of months before my first race is plenty of time to get used to it again.
I agree. I like to keep my tri bike in pristine condition so no sweat soaked rides on the trainer. I predominantly ride my road bike with powercranks until a month or so before the first race then adjust to the aero position fairly quickly. P.S. I also have a spinning bike that I use indoors and I will ride in the aero position on that for extended periods throughout the winter as well just to break up the boredom. Bottom line: I don’t think it matters much, if you are fortunate enough to have 2 bikes than why beat up the tri bike?
