Spin down/Calibration needed with Power Match?

I’m using a 4iiii Precision crank arm power meter and my Kickr using Power Match. Before every ride, I zero out/calibrate the 4iiii power meter with the 4iiii app. My question is whether I still need to do a spin down/calibration on the Kickr every few weeks or so. If so, is it better to do it through the TR software (calibration) or directly with the Wahoo Fitness app (spin down)?

Thanks in advance for any help/thoughts.

Nate said it is not required. But it may be beneficial, by getting the power values more close to each other, so PowerMatch may perform better as a result.

As to where to calibrate, I think either source is acceptable.


Yep, the calibration will be the same regardless of whether you calibrate in TrainerRoad or Wahoo :slight_smile:



Thanks @mcneese.chad and @Bryce
