I have a Favero Bepro single side power meter I every time I was going out, I could see that i was managing to get higher number then indoor with Tacx Neo. Another thing is that I was getting a new estimated FTP on my Garmin.
To test it I did a couple of indoor rides in my Neo and recording also Bepro data with garmin. I have came to a conclusion that on the Bepro the power readings was higher aound 20w that on Neo.
Anyone with similar issues? I am assuming the issue is the PM but how can I really test it?
