In Erg mode, sometimes it is difficult to maintain watts at the higher rpm’s being asked. But, I can do the watts asked at a lower cadence. So, while I struggle to maintain 200 watts at 100 rpm for a given riding segment, I can do 200 watts at 80 rpm for the same segment without the struggle. It is still pretty hard but I can do it. I can’t maintain 100 rpm over the same segment.
This makes me wonder if I am really doing 200 watts in this segment.
Does the wattage in Erg mode require the RPM being asked Or is Erg mode resistance correct regardless of RPM?
