How, when and why do I perform a Spin down Claibration.

PERFORMING A SPIN DOWN CALIBRATION

• While your VICTORY has auto-calibration after 3 seconds of free-wheeling, 
manual calibration is recommended especially when changes in the ambient 
temperature. 


• We recommend manual calibration of your VICTORY after unboxing, moving 
the unit or with the change in season. 


• Spin down calibration will ensure the trainer transmits the most accurate 
wattage numbers. 


• Before you start Zwifting or training on other apps, calibrate your VICTORY by 
performing a manual spin down calibration. 


• You can use the JetBlack Smart Trainer App or any app which supports a spin 
down. 


• Warm up your trainer for 10 minutes, ensuring that it reaches a temperature 
like that of a typical training session before proceeding with a spin down. 


• To perform spin down, download the JetBlack Smart Trainer and select SPIN 
DOWN.
