    Hello, I am just getting started. I currently use Zwift and Strava with a Wahoo Kickr. I am stuck on wheel size and heart rate threshold.

    The wheel size options are totally confusing.

    Regarding heart rate threshold, If I am understanding correctly, if I complete the 4D Power Fitness Test, the system will populate my heart rate threshold for me, correct?

    Hi Kevin! Thanks for getting in touch with us. You can just use the "default 2096mm" wheel size for the Kickr. If you record your HR on the app during Full Frontal you will be given your LTHR in the activity summary (along with your HR zones). You will need to manually enter your LTHR into your settings after the ride. Once you do that you'll have the correct zones displayed for all of your rides. Hope that helps, happy suffering!
