First ride today with a Stages power meter. I’ve been successfully using a PowerTap hub up to now with the same MacBook and dongle.
But the power kept dropping to zero very frequently. I’d say a dozen times on each lap - put it this way I didn’t once get through the KOM section without a dropout on six laps.
I moved the computer and ANT+ dongle close to the crank. It isn’t the battery - it’s new and I checked it using the Stages App on my phone.
The power was consistently going to my Garmin head unit and later I checked on the Stages App and it was also picking up the power consistently.
