Bike Gear Ratio Calculator
A precise tool.
What is the Bike Gear Ratio Calculator & How does it work?
The gear ratio of a bicycle is calculated by dividing the number of teeth on the chainring (front sprocket) by the number of teeth on the cog (rear sprocket). This ratio determines how far the bike travels with each pedal revolution, known as development.
text{Gear Ratio} = frac{text{Chainring Teeth}}{text{Cog Teeth}}
GR = Gear Ratio, CT = Chainring Teeth, CGT = Cog Teeth
Development is the distance traveled per pedal revolution and can be calculated using the formula: Development = (Chainring Teeth / Cog Teeth) * Wheel Circumference. The wheel circumference is typically calculated as pi * Diameter.

Frequently Asked Questions
How do I calculate my bike’s gear ratio?
Divide the number of teeth on your chainring by the number of teeth on your cog.
What is development in a bicycle context?
Development is the distance traveled per pedal revolution, calculated using the gear ratio and wheel circumference.
How does changing the gear ratio affect my bike’s performance?
A higher gear ratio increases speed but requires more effort to pedal; a lower ratio makes pedaling easier but slower.
Can I use this calculator for both road and mountain bikes?
Yes, the gear ratio calculation is applicable to all types of bicycles.
What does a higher gear ratio mean for my bike?
A higher gear ratio means your bike will travel farther with each pedal revolution, increasing speed but requiring more effort.
How do I find the number of teeth on my chainring and cog?
Count the teeth directly on the chainring (front sprocket) and cog (rear sprocket).
Why is it important to know my bike’s gear ratio?
Knowing your gear ratio helps in optimizing your riding style, choosing appropriate gears for different terrains, and improving overall performance.
