rode Wahoo Kickr Bike with Vectors and compared the built in PM with the Vectors.
Rode my outdoor Bike with Stages dual and Vectors.
All three were within 3% (vector end 3% higher in both tests)
So yes……. Expect them to read the same!

Presumably though a single sided crank arm power meter won't necessarily agree with the Kickr PM purely because it has to average across both legs, which aren't always equal. I'm pretty certain my left left is weaker than my right, so I won't expect it to read exactly the same as the Kickr.
