I am using an Elite TUO indoor trainer, and recently bought Assioma Favero pedals to also have a power meter for outdoor rides. Out of curiousity I checked the difference in power while doing a training on TrainerRoad. The pedals report a consistent 30 watts lower than the power of Elite TUO.
I did a calibration of the TUO before the ride, as well as a 0 offset for the pedals.
Is this to be expected, or not? I would have expected some difference but a consistent 30 watts seems odd.
