Cadence vs Speed
公式
## How Cycling Cadence Is Calculated ### Formula **Cadence (RPM) = Speed (m/min) / Development (m/rev)** Where Development = Gear Ratio x Wheel Circumference ### Optimal Cadence Most cyclists are most efficient between 80-100 RPM. Professional road cyclists typically ride at 85-95 RPM.
计算示例
Riding at 18 mph with 50/17 gearing and 2.1 m wheel circumference.
- 01Speed in m/min = 18 * 1609.34 / 60 = 482.8 m/min
- 02Gear ratio = 50 / 17 = 2.94
- 03Development = 2.94 * 2.1 = 6.18 m/rev
- 04Cadence = 482.8 / 6.18 = 78 RPM
常见问题
What cadence should I aim for?
Most riders are efficient at 80-95 RPM. Beginners tend to grind at 60-70 RPM but benefit from practicing higher cadence.
Is higher cadence better?
Higher cadence reduces muscle fatigue but increases cardiovascular demand. The optimal balance depends on the individual and the duration of effort.
How do I measure my cadence?
Use a cadence sensor attached to your crank arm, or count pedal strokes for 15 seconds and multiply by 4.
