learn.whatIsHeading
Power-to-weight ratio (W/kg) is the key cycling performance metric. The same power with less weight dramatically improves climbing speed.
公式
- W
- FTP (Functional Threshold Power) / Body weight in kg — FTP (Functional Threshold Power) / Body weight in kg
- FTP
- maximum sustainable power output for approximately 60 minutes — maximum sustainable power output for approximately 60 minutes
