I recently purchased a TACX Flux Smart T2900S and have biked a few sessions now. In one of those rides Zwift talks about erg-mode. Can somebody tell me what this is and where I can turn it off or on?
Shane Miler has a good explanation of what it is. https://youtu.be/LbeliW8uObk
Zwift also has a post about it: https://zwift.com/news/1971-the-what-and-why-of-erg-mode
David provided good links. I would just add that erg mode is only available during a structured workout. You can’t use it while free-riding or in group social rides or races. It is available during group workouts.
