I am lucky enough to have just got a Beta invite, I have a Kurt Kinetic road machine with a cycleops powerhub.
Just trying to see if it’s more useful for you if I use Zpower or real power (or can I use both in parallel) ??
Use real power, much more accurate representation of your ride. You can use one or the other, not both at the same time.
For a more accurate ride, use the power meter. However, we certainly could use the data from the Kurt Kinetic for zPower as well.
And, yes, you can only use one at a time.
