Hey everyone, I have noticed a discrepancy between my Neo 2 and my P1 pedals, so I did a test:
Here are four files comparing my Neo 2 and the P1 pedals that I have. Obviously, I need a tertiary crank-based power meter (looking at the 4iiii dual Podiiiium but will have to wait to Christmas) to see what is actually going on. First one is a 20min warmup, (after which I zeroed the P1 pedals), 2nd one is erg mode in small ring/5th gear down on the cassette on the Tacx app, (no zeroing between rounds), 3rd one is erg mode in big ring, 4th one is on Zwift with Zwift record power over BTE and my Garmin tracking P1 pedals over ANT plus. I tried to keep cadence close to 95 during tests 1-3, but on Zwift this was harder.
I hope you all can make sense of this. Which power meter should I use in Zwift (I will lose a lot of watts if I do)? Which one do you think is more reliable? Should I contact Garmin to see if I can get a replacement? Is this normal?
My observations: an expected ~6 watt difference between them in small ring. In big ring, larger wattage difference and increases over with higher wattages. On Zwift, huge difference. This was free ride mode with threshold surges and a tempo section at 300 watts.
Oh for what its worth, no issues with my gen 1 neo and the p1 pedals, and when I had a quarq red, small difference between pedals and crank but consistent and only 3-6 watts. Unfortunately, I do not have either right now to do more testing.
