1. What is Gear Ratio?

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.

2. How Does the Calculator Work?

The calculator uses the gear ratio formula:

Where:

• Chainring Teeth — Number of teeth on front chainring
• Cog Teeth — Number of teeth on rear cog

Explanation: A higher ratio means more speed per pedal revolution, while a lower ratio means easier pedaling.

3. Importance of Gear Ratio

Details: Gear ratio affects your bike's acceleration, top speed, and how easy it is to pedal. Choosing the right ratio is crucial for optimal performance in different terrains.

4. Using the Calculator

Tips: Enter the number of teeth on your chainring and cog. Both values must be positive integers (typically between 20-50 for chainrings and 10-50 for cogs).

5. Frequently Asked Questions (FAQ)

Q1: What's a good gear ratio for dirt bikes?
A: It depends on terrain. For technical trails, lower ratios (2.0-2.5) are better. For open terrain, higher ratios (2.5-3.5) provide more speed.

Q2: How does gear ratio affect climbing?
A: Lower ratios make climbing easier by reducing the force needed per pedal stroke, allowing you to maintain cadence on steep inclines.

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. Gear ratio is more universal for comparison.

Q4: Can I use this for mountain bikes?
A: Yes, the calculation works the same for any chain-driven bicycle.

Q5: How does changing sprockets affect ratio?
A: Increasing chainring teeth or decreasing cog teeth increases ratio (higher speed). Decreasing chainring teeth or increasing cog teeth decreases ratio (easier pedaling).
