Hi
I moved my newton across to a new bike and seem to be having trouble calibrating it. It's definitely reading higher power than I can produce, maybe 60-80% higher than it should.
I've tried all the normal things, cal ride, cal tilt, cal wind, even a different mount.
Attached is a ride file from a out and back ride. Any Ideas?
Thanks

Re: New Bike Config Problem
Somehow your Crr was adjusted upwards from 0.0054 (normal road) to 0.035...(quicksand).
I put your Crr back to a normal level. Load this profile into your Newton and all will be well.

Thanks I'll give that a try
Re: New Bike Config Problem
Thanks for your help.
I've used the updated profile and I still seem to have the problem (350-500w being displayed on the flat @32-36kph).
This weekend I did two solo largely out and back rides in low wind and Issac doesn't recommend any significant change.
I've attached the ride files. Any ideas?
Thanks again

Re: New Bike Config Problem
I'm not sure how it happened but the rides you have show a Crr of 0.03. That would be like riding through quicksand...
Returning your rides to a "normal" road resistance of 0.0054 returns your rides to reality.
I would do a new cal ride.
