1. What is Gear Ratio?

The 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 simple gear ratio formula:

Where:

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

Explanation: A higher gear ratio means more speed per pedal revolution but requires more effort, while a lower ratio provides easier pedaling but less speed.

3. Importance of Gear Ratio

Details: Choosing the right gear ratio is crucial for optimizing performance based on terrain, rider strength, and desired speed. It affects acceleration, top speed, and pedaling efficiency.

4. Using the Calculator

Tips: Enter the number of teeth on your chainring and cog. Both values must be positive integers (typically between 20-60 for chainrings and 10-50 for cogs).

5. Frequently Asked Questions (FAQ)

Q1: What's a typical gear ratio for dirt bikes?
A: Common ratios range from 1.5 to 4.0, depending on the terrain and riding style.

Q2: How does gear ratio affect climbing ability?
A: Lower ratios (smaller chainring or larger cog) make climbing easier by reducing the effort needed per pedal stroke.

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 other types of bikes?
A: Yes, the same calculation applies to road bikes, mountain bikes, and other chain-driven bicycles.

Q5: How often should I change my gear ratio?
A: Adjust when changing terrain types significantly or if you're consistently struggling with hills or lacking speed on flats.
