Frequently Asked Questions
How do you calculate speed from cadence and gearing?
Speed (km/h) = (Chainring Teeth ÷ Cassette Teeth) × Wheel Circumference (m) × Cadence (RPM) × 60 ÷ 1000.
What is a good cycling cadence?
Most experienced cyclists aim for 85-95 RPM on flat terrain to optimize cardiovascular efficiency and reduce muscular strain.
