Looking for suggestions on how to calibrate my Newton for a Fat Bike. I did a calibration ride on a flat snow covered road and got a negative Crr.

Please post your Cal ride file.

The first file (11-29-2013) is the original. The second is on a joined file, I don't have the original cal ride but it was for the first 2 miles. As you can see I manually tweak the Crr to about 0.03 to give me an average power to match my RPE for the ride.

For another Cal ride I got -0.0142 Crr. My wheels push me! :)

Corrected profile is attached.

I set Crr to 0.008
