About Cadence and Speed

The relationship between cadence, gear ratio, and speed is fundamental to cycling performance. Understanding these relationships helps optimize your pedaling efficiency and power output.

Key Formulas:

Speed (mph): (Cadence × Gear Ratio × Wheel Circumference) / 1056
Cadence (RPM): (Speed × 1056) / (Gear Ratio × Wheel Circumference)
Gear Ratio: Chainring Teeth ÷ Cassette Teeth
Gear Inches: (Chainring ÷ Cassette) × Wheel Diameter

Gear Classifications:

High Gear: 100+ gear inches (fast, hard to pedal)
Medium Gear: 70-100 gear inches (balanced)
Low Gear: Below 70 gear inches (easy, slow)
