i calibrate before every ride. tends to be -18 to -20. around there. consistently. every ride. in and outdoors.
flew to florida from indiana. calibrated every ride. typical zero numbers. power felt accurate.
flew back from florida. and now its zeroing at +48 to +50. fine. no big deal. i thought. doing whorl and it is toooo easy. heart rate is like 20 bpm low. i know he is not an indicator of effort. but power effort seems too easy.
i have calibrated with trainer road multiple times. updated firmware and calibrated with quarq iphone app.
battery is at 85%. i did wash the bike in florida but i washed it just like i have every time since i got the power meter. im experiencing zero signal dropouts. maybe new battery anyways?
bike seemed to be unharmed from luggage handlers. it was packed in an evoc pro bike bag with plenty of bubble wrap.
Do you have a smart trainer or any other source of power that you could verify with? If not, perhaps you have a friend with a smart trainer or power meter pedals that you could use to help you verify the extent of the power offset? Knowing this information would be useful to send Quarq Support if you decide to go that route.
I haven’t personally seen anything like the issue you are describing, but from a little digging I was able to find some information about verifying your Quarq power meter’s slope. This is a somewhat complicated process, however, I’ve included links below that will be good resources for you.
This video helps to explain how the process works:
Like I said, I don’t have personal experience with this issue, but this is just one possible lead that you could investigate. If I were you, I would determine the amount of offsetyour power meter is experiencing, and then send an email to Quarq Support before going down the slope rabbit-hole.
