Tacx Flux S ERG problems at low cadence

I’m having problems with my Tacx Flux S when training using erg mode. Anytime the training requires me to do low cadence (below 70) with any power above 100w, the trainer is unable to generate that power. However, with cadences above 70, I do not have any issue. Am I doing something wrong or do I have a faulty Tacx?

Hello Armando.

Have a look at this thread: Newb cannot maintain 80 rpm and power level at same time

The TL;DR: what bicycle are you on and what gears are you using? Small front chainring and somewhere toward the middle of the cassette is likely optimal.
