Cycling Power計算機とは何ですか
A Cycling Power 計算機 estimates the wattage required to maintain certain cycling speeds based on rider 体重, bike 体重, terrain, and wind resistance.
使い方
Enter your 体重, bike 体重, speed, 成績 (slope), and wind conditions. The 計算機 shows the power output required in watts.
よくある質問
What is a Cycling Power Calculator?
A tool that estimates the power output (measured in Watts) a cyclist needs to produce to maintain a specific speed under certain conditions, such as gradient, wind, and surface type.
What inputs are required to calculate power?
Typically, you need your total weight (rider + bike), your speed, the gradient of the road (slope), the rolling resistance coefficient (tire type), air density, and your aerodynamic drag (CdA).
What is Crr (Coefficient of Rolling Resistance)?
Crr represents how much friction exists between your tires and the road. Lower values (e.g., 0.004) indicate high-quality road tires on smooth asphalt, while higher values indicate knobby tires on rough surfaces.
How does gradient affect power output?
Gradient is usually the most significant factor. As the slope increases, the force of gravity pulling you backward increases exponentially, requiring a massive increase in wattage to maintain speed.
What is CdA (Drag Coefficient)?
CdA stands for Coefficient of Drag Area. It combines your shape and your frontal area. A lower CdA (e.g., in an aerodynamic tuck position) requires significantly less power to overcome air resistance at high speeds.
Why is the calculated power different from my power meter?
Calculators are theoretical models. Real-world variables like drafting, changing wind gusts, road surface bumps, and chain friction loss are hard to quantify perfectly, so actual readings may vary slightly.
Does the calculator account for drafting?
Standard calculators usually assume a rider is alone in the wind. To account for drafting, you would manually reduce the CdA (Drag Coefficient) input to simulate riding behind another cyclist.
