When to calibrate the trainer

Power

Some trainers need calibration or spindown to measure power better. Others self-calibrate or do not require it in the same way.

Check whether your model recommends calibration.
Warm up the trainer for a few minutes if the manufacturer asks for it.
Do a spindown from the manufacturer’s compatible app if appropriate.
Do not calibrate every five minutes searching for the perfect number.
Compare sensations and data after calibrating.
If you do not know whether your trainer needs it, ask providing the exact model.
