Zwift How-To: Calibrating Your Smart Trainer

on January 09, 2018

Calibrating your smart trainer is critical to getting accurate readings on Zwift. Do it often, and Zwifting will be better thanks to good data. Neglect regular maintenance and you’ll get inconsistent and incorrect numbers.

Although we encourage riders to calibrate before every ride, doing so for wheel-on trainers is paramount. Wheel-on trainers measure power based on friction and need regular TLC.
Some riders with direct drive trainers calibrate less often. But, even most of these riders know that if the trainer is moved, undergoes significant temperature changes, or is in direct sunlight, calibration is necessary.

Regardless of what kind of trainer you have, you should warm-up the trainer for about 10 minutes before calibrating. After the trainer is warmed up, Zwifters with a Cyclops Hammer, Wahoo Kickr, or Wahoo Kickr Snap can calibrate in game. Watch the video or follow the directions below.

Don’t have one of the trainers listed above? Just follow the manufacturer’s instructions — most have an app.
