I've been riding on my Kickr trainer and so far matching the power almost exactly as my Vector 2 did on the same trainer.
Human beings and chimpanzees share about 98% of their DNA. Sometimes knowing what's different is more interesting than knowing that they're mostly the same.
I tried my best to find the differences. First I rode a simple 20 minutes using the Vector 2. Then I immediately took them off and put on the brand new PowerTap P1's and did the exact same 20 minute ride. Data was almost exactly the same except for a little warm up drift from the KIckr. I wasn't about to then try the Vector 2 again since it's a PIA to torque them down while on the trainer. Obviously a big advantage of the P1's and newer Vector 3 to not have to worry about the torque.
The Vectors do give a ton of cycling dynamics that's fun to look at, but really haven't been able to use that info to make me a better cyclist.
After a much longer ride yesterday, I have a lot of confidence that I'm getting nearly the same power numbers so I won't have to worry about different FTP's depending on which pedal PM's I use.
