    I tried this with Wahoo Kickr and the resistance to get up to speed was too high. I've gone through this process mutliple times using both Wahoo utility app and TrainerRoad and had no problems - have I done something wrong? what's different with your system?

    I just swapped bikes and when I tried to calibrate with the new bike on my Wahoo Kickr I can't pedal fast enough to reach the specified speed. I didn't have trouble calibrating eith my Kickr in the past.

    I've found a fix for this.

    Open up the calibration in CVT, then while it is open run a calibration on iPhone utility app - the CVT calibration seems to mirror it and CVT worked fine after that.
    I'm running CVT app on Windows 10 laptop with ANT+ dongle and iPhone 4S with Bluetooth.

    Hope this helps

    Thanks for the tip Anth! I'm going to try again this evening. I realized I forgot to set the gear ratio for the new bike. That may have been the problem since it has a different gear set than the previous bike. If that doesn't work, I'll try your solution :-)
