Frequently Asked Questions

About cycling power

What is FTP?

Functional Threshold Power—max average power for about one hour.

How accurate is this estimate?

It’s physics‑based; wind, position, and gear affect reality.

What is W/kg?

Power normalized to weight—key for climbing performance.

Why does aerodynamics matter?

At high speeds, most power offsets air resistance.

Do I need a power meter?

For precision yes; this tool gives estimates without one.

How often to retest FTP?

Every 4–8 weeks, or after training blocks.

Does bike weight matter?

Yes—affects gravitational and rolling resistance.

What’s a typical CdA?

Around 0.30–0.40 m² for road positions; varies widely.

Will tire pressure change power?

Rolling resistance changes slightly with tire/pressure/surface.

Best workouts for power?

Threshold intervals, VO₂ sets, and strength training.
