I recently put my Garmin Vector pedals on my “outdoor bike” and put my Powertap hub on my trainer bike. I use a Wahoo Kickr Snap, PowerTap Hub G2, and TrainerRoad. I currently have power matching set to ON (the new version of powermatch, not “legacy”).
My problem is this: I can’t for the life of me dial it in so my power feels accurate. Today I did an 8-minute FTP test, where I should be able to hold around 190 for each 8 minute interval. I would settle in at that power and very quickly my cadence would just get too high to maintain, so I’d stop for the wheel to slow down, then start up again. I even tried bumping up to 105%, then 110%, but without fail I’d out-spin the test. 190 felt like a breeze (which it really shouldn’t). Obviously, the results were very inaccurate since I kept having to stop pedaling!
That said, my workouts have felt way too easy as well.
Thoughts on the best way to remedy the situation?? I don’t want to have to go back to the garmin pedals, but I will if needed.
