Hi
Today I performed a workout (ERG Mode), but each time the target watt level was reached it felt like the resistance dropped by 50% and the trainer started to increase it again.
If the desired effect was 135 watts, as soon as I hit that number - the trained immediately lowered the resistance so much that the generated effect dropped to approx. 80 watt given the same cadence.
It went on for the entire workout.
I’ve used the same phone (Android S10 with Zwift over bluetooth) since I got the trainer and it have worked perfect every time - until today
Zwift or trainer?
