Chainring Ratio Calculator

Formula

The formula to calculate the Chainring Ratio (R) is:

\[ R = \frac{T_c}{T_s} \]

Where:

Chainring Ratio (R): A measure of the mechanical advantage provided by a bicycle’s drivetrain. It determines how many times the rear wheel will turn for each complete revolution of the pedals.
Number of Teeth on Chainring (T_c): The number of teeth on the front gear (chainring).
Number of Teeth on Rear Sprocket (T_s): The number of teeth on the rear gear (sprocket).

Let's say the Number of Teeth on Chainring (T_c) is 50 and the Number of Teeth on Rear Sprocket (T_s) is 25. Using the formula:

\[ R = \frac{50}{25} \]

We get:

\[ R = 2 \]

So, the Chainring Ratio is 2.
