Getting Your FTP Estimate
The device uses your user profile information from the initial setup to estimate your functional threshold power
(FTP). For a more accurate FTP value, you can conduct an FTP test using a paired power meter and heart rate
monitor (Conducting an FTP Test, page20).
Select > My Stats > Power > FTP.
Your FTP estimate appears as a value measured in watts per kilogram, your power output in watts, and a
position on the color gauge.
