I was riding the Sand and Sequoias route this evening and on the rolling hills I kept having my power drop to zero every time I would pedal through the resistance of the next incline at speed and in a high gear.
Most of the troubleshooting advice seems to suggest BLE issues, but I would suspect that would be much more random. This was very consistent. Every single time I was cruising downhill on Titan’s Grove and keep pedaling through resistance of the next hill my power would rise to 250-500 watts then suddenly drop to zero watts for a couple seconds. It seems unlikely to be a tire slippage issue either as the flywheel would keep supplying at least some watts against the resistance (also, I didn’t feel or hear any slippage, subjectively it felt like I was applying similar levels of power to the pedal throughout the events).
Is it possible that this is just Zwift trimming what it sees as outlier power readings? My FTP is pretty low (mostly because I just started this week and am out of shape but) partly because I’ve been sharing the bike with my wife and kept forgetting to readjust the seat before riding. My ride this evening was one of the first where I both had the seat adjusted correctly/could really apply full power to the pedals and was also hitting some inclines/resistance on the hills.
Activity is here. I can provide the log file if it would help, but I don’t see any messages that coincide with the power drops.
I’m using a 26" MTB with city tires on a Kurt Kinetic Rock and Roll Control. I’m trying to not get too crazy with my expectations from a wheel-on trainer before the trainer tire I ordered arrives, but this doesn’t seem to be a tire issue from what I can tell.
Thanks in advance for any help.
