If you’re new to ERG mode or have been using ERG mode for a while and switch between erg mode and slope mode or manual mode, you might have noticed that ERG mode might feel a little bit harder for the same effort.
In this video, I took a detailed look at ERG mode and why it might feel harder to do a workout in ERG mode when indoor cycling than slope mode, resistance mode or ride outside.
You will also see how a smart trainer reacts differently when in ERG mode when in the small chainring compare to the big chainring.
For this experiment, I did a 3×15 minutes workout twice using two different trainers.
- The first 15 minutes was done in the big chainring with ERG mode turned ON in Zwift.
- The second 15 minutes was done in the big chainring with ERG mode turned OFF.
- The final 15 minutes was done with ERG mode turned ON but switched to the small chainring.
