Using KM40 on trainer

I am wondering if using my KM40 on there computrainer puts undue stress on the frame? With the rear wheel fixed the frame seems to flex a bit. If I ride it this way am I shorting it’s life? What do you guys think?

Thanks

I have been riding mine for over 2 yrs on CT with no issues. Besides they come with a lifetime warranty on the frame.

I too have used my KM40 on a trainer and on rollers with no problems (but for some boredom…relieved through some good race videos). Although, the aero bars make a roller a bit more challenging.

Have wondered the same thing, but no problems yet for me, either. Do 3 of my 4 weekly rides on my KM40 set in a Kinetic trainer. Bike is 1.5 years old.
