I'm new to trainers and today was my first workout on my new kickr. It's my understanding that no calibration is needed or even possible. Yet it was extremely difficult to pedal even using the front small ring w the rear big ring. It improved some when I shifted down the rear cassette a ring or 2 and then shifted back up. But the whole ride was as if the Kickr thought I was using the front big ring but in reality I never had enough leg power to use it. (my FTP is only c.185 but I was dying w very easy gearing).

I was also using my edge 830 w Assioma pedal power meters. They had my typical power at 150 watts vs on Zwift/Kickr I was seeing 135 watts. My legs were feeling 220 watts!

So it was over-strenuous pedaling and Zwift/Kickr seemed to be under-rating the power.

More difficulties w my first trainer workout experience - did not see Grade nor Cadence nor PowerBalance on-screen.

I sure miss the open road!

(BTW, I did clean my chain and gears and did not re-lube them - it was almost a 2-hour ride)
