How do you calculate gear inches on a Rohloff hub?
Calculating gear inches on a Rohloff hub involves a simple mathematical formula that takes into account the size of the wheel and the number of teeth on the front and back sprockets. To start with, it is important to note that gear inches is a term used to describe the distance traveled in inches with one rotation of the pedals.
To calculate gear inches, first, determine the size of the wheel in inches. For example, let us assume that the size of the wheel is 26 inches. Then, determine the number of teeth on the front sprocket, also called the chainring. Let’s say the chainring has 44 teeth. Next, determine the number of teeth on the rear sprocket, also called the cog.
Let’s assume the cog has 16 teeth.
Using these values, plug them into the formula:
Gear Inches = (wheel size in inches X chainring teeth) / cog teeth
Substituting the values, we get:
Gear Inches = (26 X 44) / 16
Gear Inches = 71.5
Therefore, with this configuration, one revolution of the pedals would make the bicycle travel 71.5 inches.
It is important to note that the Rohloff hub has a wide range of gears, and therefore, the number of teeth on the sprockets can vary depending on the rider’s preference. The formula for calculating gear inches remains the same, regardless of the number of teeth on the sprockets.
