Watts readings

Hi, I don’t have a smart trainer, just a cadence and speed sensor using ANT+

I noticed that my Watts output jumps from over 100 to under around 60-70 quite often then back up to 100, while maintaining a steady RPM and not changing gears, is this normal?

Speed doesnt appear to be effected?


Check and see if the gradient changes. It’s the mini map in top right corner. If your speed is staying the same and you begin an ascent, you should get a spike in watts.
