Let's compare power data from the Wahoo Kickr Snap indoor smart bike trainer to the 4iii Shimano Ultegra R8000 Precision Left Side crank power meter. In this video I will present power data from a few different tests including average power from 1 minute at 100 watts, 200 watts, 300 watts, and 10 minutes free-riding in Zwift.
Testing notes (for those who are curious). The Kickr Snap was warmed up for 10 minutes prior to performing a calibration spindown via Zwift. I am using a trainer tire and verified pressure was 110 PSI. The knob on the Kickr Snap was rotated two full turns after making contact with the trainer tire. The 4iii power meter was calibrated via the featured Garmin Edge 520 plus prior to testing.
I'm hoping I will be able to perform this test again with a dual sided power meter for a more accurate comparison, but for now the numbers are correlating well between the 4iii and Wahoo.
