1. What is Sprint Velocity?

Sprint velocity measures how fast a bike is moving during a sprint, calculated from wheel circumference and pedaling cadence (RPM). It's a key metric for cyclists to evaluate their sprint performance.

2. How Does the Calculator Work?

The calculator uses the sprint velocity equation:

Where:

• \( v \) — Sprint velocity (m/s)
• \( wheel\ circumference \) — Distance covered in one wheel revolution (meters)
• \( RPM \) — Pedaling cadence (revolutions per minute)

Explanation: The equation converts RPM to revolutions per second and multiplies by wheel circumference to get speed in meters per second.

3. Importance of Sprint Velocity Calculation

Details: Knowing sprint velocity helps cyclists optimize gear ratios, improve sprint technique, and track performance improvements over time.

4. Using the Calculator

Tips: Enter wheel circumference in meters and RPM. Typical wheel circumference is ~2.1m for 700c wheels. Sprint RPM is typically 100-150 for trained cyclists.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure wheel circumference?
A: Measure the distance the bike travels in one complete wheel revolution, or calculate from wheel diameter (circumference = π × diameter).

Q2: What's a good sprint velocity?
A: Elite sprinters can reach 15+ m/s (54+ km/h). Amateurs typically reach 10-13 m/s (36-47 km/h).

Q3: Does tire pressure affect the calculation?
A: Yes, higher pressure reduces rolling resistance but can slightly decrease circumference due to less tire deformation.

Q4: How accurate is this calculation?
A: It provides theoretical maximum speed. Actual speed may be slightly lower due to factors like wind resistance and drivetrain losses.

Q5: Can I use this for gear ratio planning?
A: Yes, combine with gear ratios to determine optimal cadence ranges for different speeds.
