Hello,
I’ve just bought my first power meter. I went with the 4iii. I can’t justify the cost of a dual leg meter. I want to use it for pacing my outdoor rides and interval training etc. I have a number of options of calibrating (or not) the power between the Kickr Core I use with TrainerRoad and the 4iii and wondered which you guys thought would be best.
-
Trust that the Core and 4iii power readings will be roughly the same and use my Core/trainerroad FTP for outdoor rides. I think I probably have a difference between left and right legs, because I can feel my right spins in smooth circles whereas my left does not. So option 1 is probably a bad idea.
-
Do an outside FTP test on the 4iii and use that result for outdoor rides. Then, If my FTP has improved after doing a TR ramp test, I can adjust the outdoor result by the same number of watts.
-
Put 4iii on my Kickr Core bike and look at the difference in power readings and use 4iii’s scale factor to match them as best as I can. If I do this option, should I measure the difference between max power, average power or ftp?
Many thanks
James
