It's pretty strange. Maybe I will arrange the wahoo unit first for checking if the cadence in my case is correct. I assume the difference is noticeable quickly?
Could please verify the data sample rate for me? Simple read FIT file with a record with your SRM power meter. In my case, it's every 1 second but I use Garmin.

This could be an option too. Unfortunately, I can't find anything cheap. Maybe looking in a wrong place but I see prices above $1000 For a good price I could go with wahoo/garmin on my road/cx bikes and keep PC7 for track only. As I would need recollect all mounts for wahoo anyway (integra stem, oval pro missile tt, saddle rail) I could go with SRM versions. But it's definitely not worth $1000.
