I am new to power meters. I purchased a Favero BePro model (just the left pedal) and have been using it, in part, in connection with TrainerRoad.

Perhaps my perceptions are skewed, but it appears that my watts go down when I shift up to harder gears. If my cadence remains comparable, shouldn't my power be going up given that I'm having to push down harder on the pedals? My speed goes up, but my power declines. It also seems strange that when I shift down to easier gears my power shoots up--sometimes dramatically--with little effort and easy pedaling. It just doesn't seem like my watts coincide with my effort.

Does this sound normal, or should I check with the vendor to get this looked at?

Thanks for your feedback.
