Please check MTB calibration: power too high

Post by Etupes25 »

Hello,
I have not succeeded in creating a good profile for my MTB. The power reading looks abnormally high (compared with perceived effort and the readings on my road bike).

Can you please check my Cda and crr values? The Cda looks similar to my road bike, but my riding position is very different obviously. The crr of 0.01+ seems high. The Crr for my MTB tires are more in the 0.007 range.

I did the calibration on the same road I did the road bike calibration on.

Your Crr is too high.

Corrected profile is attached.
