FTP (Functional Threshold Power)

FTP represents the highest power you can sustain for approximately one hour. It's the gold standard for cycling performance measurement and training zone calculation.

Power-to-Weight Ratio

Power-to-weight ratio (W/kg) is crucial for climbing performance and overall cycling ability. Higher ratios indicate better performance, especially on hills.

Training Zones

Power-based training zones help optimize your workouts for different physiological adaptations, from recovery rides to high-intensity intervals.

Performance Levels

Cycling performance levels range from recreational to world-class, based on power output, power-to-weight ratio, and time trial performances.
