Getting Your FTP Estimate
Before you can get your functional threshold power (FTP) estimate, you must pair a chest heart rate monitor and power meter with your device (Pairing Your Wireless Sensors), and you must get your VO2 max. estimate (Getting Your VO2 Max. Estimate for Cycling).
The device uses your user profile information from the initial setup and your VO2 max. estimate to estimate your FTP. The device will automatically detect your FTP during rides at a steady, high intensity with heart rate and power.
