• I've got a Powertap and now a Quarq DZero. I want to test both simultaneously so I can see how much higher (I assume) the crank-based PM will read by.

    Yes, essentially I basically want to avoid having to do another FTP test...

    Powertap is Ant+ only, DZero does Bluetooth - So if I run my PT to dispaly on the Garmin, is there an iOS app which can give me live/3s/10s power data from Bluetooth? I've just checked an TrainerRoad only works with Ant+...

  • Got a turbo? Just ride at a set speed on the turbo and record the power required with both. Do a few runs to take an average.
