Bike Leverage Ratio Calculator

Formula

The formula to calculate the Leverage Ratio (LR) is:

$LR = \frac{RWT}{SS}$

Where:

$LR$ is the leverage ratio
$RWT$ is the rear wheel travel (mm)
$SS$ is the shock stroke (mm)

What is a Bike Leverage Ratio?

The leverage ratio of a bike is a measure of how much the rear wheel travel is amplified by the shock stroke. It is an important factor in the design and performance of a bike’s suspension system. A higher leverage ratio means that the rear wheel travel is greater for a given shock stroke, which can result in a softer and more responsive suspension. Conversely, a lower leverage ratio means that the rear wheel travel is less for a given shock stroke, which can result in a firmer and more stable suspension. Understanding and optimizing the leverage ratio is crucial for achieving the desired balance between comfort, control, and performance in a bike’s suspension system.

Example Calculation

Let's assume the following values:

Rear Wheel Travel (RWT) = 150 mm
Shock Stroke (SS) = 50 mm

Using the formula to calculate the Leverage Ratio (LR):

$LR = \frac{RWT}{SS} = \frac{150}{50} = 3$

The Leverage Ratio (LR) is 3.
