1. What is Torque in Cycling?

Torque in cycling refers to the rotational force applied to the pedals. It is calculated as the product of the force applied perpendicular to the crank arm and the length of the crank arm.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( T \) — Torque (Nm)
• \( F \) — Force applied perpendicular to the crank (N)
• \( r \) — Crank arm length (m)

Explanation: The equation calculates the rotational force generated by the cyclist, which is a key factor in power output and pedal efficiency.

3. Importance of Torque Calculation

Details: Torque measurement is essential for optimizing cycling performance, understanding power output, and improving pedal stroke efficiency.

4. Using the Calculator

Tips: Enter force in newtons (N) and crank arm length in meters (m). All values must be valid (force > 0, radius > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is typical torque range in cycling?
A: Torque values vary significantly based on rider strength and cycling conditions, but typically range from 20-80 Nm for most cyclists.

Q2: How does torque relate to power in cycling?
A: Power is calculated as torque multiplied by angular velocity (cadence). Higher torque at the same cadence results in greater power output.

Q3: Why is crank length important for torque calculation?
A: Longer crank arms provide greater mechanical advantage, allowing more torque to be generated with the same force application.

Q4: How can I measure pedal force accurately?
A: Professional cycling power meters measure force directly, but for estimation, you can use average force values based on your weight and pedaling technique.

Q5: Does higher torque always mean better performance?
A: Not necessarily. Optimal torque depends on cadence, gearing, and riding conditions. Extremely high torque can lead to early fatigue and muscle strain.
