So I am coming up on the end of my current training plan and I plan on switching from my old Garmin Vector 3 dual-sided pedals to a new set of Favero Assioma dual-sided. I am curious if I need to do a ramp test or can I just let the AI do it’s thing?
I am waiting to switch until after my A-event
Test both against a smart trainer.
Just let it do its thing. Expect some kind of change in FTP and go with it because it doesn’t matter what the number is.
I would probably do a 30min endurance ride after swapping them over, to make sure they are set up, paired, power matched etc. youd notice if there was a massive issue.
I agree with both takes here.
Sometimes it’s nice to test two power sources against each other to know how differently they read, but at the end of the day, if you’re going to commit to making the switch, it really doesn’t matter too much.
TR AI will figure it out based on how you perform in your upcoming workouts. 
Thanks for the suggestions. I may try testing both against my kickr bike. If they are close, I may keep the vectors on the kickr bike and the assiomas on the madone
