I have a Tacx Neo Smart that I’ve been using with Zwift for the past 9 months with no issues, for both workouts (in erg mode) and just ride.
Yesterday, I rode the 2x15 FTP interval workout and everything worked fine. During the FTP interval, resistance (erg mode) was “normal” so I would hit FTP level in my normal cadence (upper 70’s to mid 80’s).
Today, I rode the 2x20 FTP workout. Everything was fine during the warmup but during the FTP interval, resistance was set very low so that I had to pedal 100-110 rpm to reach FTP level. That was no fun and I stopped after 10 minutes.
Does the 2x20 FTP normally set the resistance super low to require a high cadence? It seems strange that 2x15 FTP was fine and 2x20 FTP was not.
Is there something I can do to get it to give me resistance such that I can hit FTP with my normal cadence?
