Perform the Manual Zero process in the AXS App or a compatible cycling computer. It may be called a 'Power Meter Calibration' (or similar) within the owner's manual of your cycling computer. The Rival spindle-based power meter should have Manual Zero performed before each ride for the best accuracy.
Manual Zero Calibration Steps:
1)Ensure you are off the bike and unclipped from the pedals.
2)Place the drive-side crank arm in the 6 o'clock position.
3)Complete the calibration process following one of the steps below. During the calibration process, do not move or touch the crank.
- In the AXS App, press "Set Zero." Pressing "Set Zero" will complete the calibration process.
- In your cycling computer, initiate the 'calibrate' command as instructed in its owner's manual. Within 3-5 seconds, the cycling computer should indicate 'Success' and often display the Zero Offset number.
Or, watch the Rival Power Meter Calibrations video to view the Manual Zero calibration process.
Learn more about your calibration numbers in the "What is a good Zero Offset number?" article.
NOTE: Magic Zero is unavailable on the Rival DUB-PWR spindle-based power meter.
