I recently started cycling again after stopping five years ago. New road bike, but using old Garmin 510 with no issues. I just purchased Favero Assioma duo power meter pedals. After going for a ride with the PM and the 510, I noticed my timer stopped at approximately 1:03 into ride. It was still displaying power, speed, cadence etc. This was at a good speed, I wasn’t slowing or stopping. PM for cadence, speed from 510 gps. I figured older 510 unit was the problem, so I purchased a new 830. Guess what same issue with two rides, timer stops at 1:03. I then need to stop and save ride so it will record data again. With the new 830 I tried adding my Trek duo tap sensor for speed, same problem. Then I tried using the Garmin cadence sensor that came with the bundle and still timer stops at 1:03. Any clue? Waiting to hear back from Favero.
