Bike Leverage Ratio Formula
The following formula is used to calculate the leverage ratio for a given rear wheel travel and shock stroke.
LR = RWT / SS
Variables:
- LR is the leverage ratio
- RWT is the rear wheel travel in millimeters
- SS is the shock stroke in millimeters
To calculate the leverage ratio, divide the rear wheel travel by the shock stroke.
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.
How to Calculate Bike Leverage Ratio?
The following steps outline how to calculate the Bike Leverage Ratio.
- First, determine the rear wheel travel (RWT) in millimeters.
- Next, determine the shock stroke (SS) in millimeters.
- Finally, calculate the leverage ratio using the formula LR = RWT / SS.
- After inserting the values and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Rear Wheel Travel (RWT) = 150 mm
Shock Stroke (SS) = 50 mm
