About Bike Cadence & Speed
What is Cadence?
Cadence is the rate at which a cyclist turns the pedals, measured in revolutions per minute (RPM). Most recreational cyclists maintain 60-80 RPM, while competitive cyclists often pedal at 90-110 RPM.
Optimal Cadence Range
- • Recreational: 60-80 RPM
- • Training: 80-100 RPM
- • Racing: 90-110 RPM
- • Time Trial: 100-120 RPM
Calculation Formula
Speed = π × (wheel diameter + 2 × tire size) × (chainring/cog) × cadence
Benefits of Higher Cadence
- • Reduced muscle fatigue
- • Better cardiovascular efficiency
- • Improved pedaling smoothness
- • Lower risk of knee injury
Training Tips
Cadence Training
- • Practice high-cadence intervals (100+ RPM)
- • Use a metronome or cadence sensor
- • Focus on smooth, circular pedaling motion
- • Start with shorter intervals and build up
Gear Selection
- • Lower gears for higher cadence
- • Find your optimal power/cadence balance
- • Adjust gearing for terrain and conditions
- • Practice shifting to maintain cadence
Monitoring Progress
- • Use a cadence sensor for accurate data
- • Track average cadence over rides
- • Note efficiency improvements
- • Compare different gear combinations
