I have a new 1050 for few weeks and noticed that power readings are possibly higher by 10% compared to my old 530. There is no way my power would jump by 10% in a matter of a week... (although it would be nice ;-).
So today I have used 1050 and 530 on the same MTB ride, both connected to the same Quark power meter, and yes, the power reading was very different.
Average Power
1050 = 206 W
530 = 189 W
Max Power
1050 = 874 W
530 = 815 W
Attached is the image with more details.
Both units have "Power Averaging" set to "Include Zeros".
Such discrepancy is bad. Anyone with any ideas?
