Gear Ratio Formula:
From: | To: |
Gear ratio is the ratio of the number of teeth on the chainring to the number of teeth on the cog. It determines how many times the rear wheel turns for each pedal revolution.
The calculator uses the gear ratio formula:
Where:
Explanation: A higher gear ratio means more distance covered per pedal revolution but requires more effort. Lower ratios make pedaling easier but cover less distance per revolution.
Details: Gear ratio helps cyclists choose appropriate gearing for different terrains and riding conditions. It's crucial for optimizing pedaling efficiency and speed.
Tips: Enter the number of teeth on your chainring and cog (both must be positive integers). The calculator will compute the gear ratio.
Q1: What's a typical gear ratio for road bikes?
A: Common ratios range from about 2.0 (easy climbing) to 4.0+ (hard sprinting).
Q2: How does gear ratio relate to speed?
A: Higher ratios allow higher speeds per pedal revolution but require more power. Lower ratios are better for climbing.
Q3: What's the difference between gear ratio and gear inches?
A: Gear inches incorporates wheel size, while gear ratio is purely based on teeth count.
Q4: Can I use this for any bicycle?
A: Yes, it works for any chain-driven bicycle (road, mountain, hybrid, etc.).
Q5: What's considered a "good" gear ratio?
A: It depends on your fitness, terrain, and riding style. There's no single "best" ratio.
