Hi all,

In an effort to supplement my training for the upcoming MS150 ride in my area, I tend to fit in some Spinerval workouts on my trainer during the week when I can't get out on the road. For some reason though, when my bike is on the the trainer my front deraileur never seems to shift very well. If I take it off the trainer and go ride outside it seems to shift well again. I'm not sure what info would be pertinent at this point. I ride a 2008 Cannondale CAAD9 R5. All cables were replaced about a year and a half ago. FD is Shimano 105, 105 Double and 10 spd rear cassette with Ultegra RD.

Just seems strange that it shifts well on the road and not so well on the trainer.

Thanks in advance,
Tim
