What is a Gear Ratio Calculator?

A gear ratio calculator helps cyclists understand how different gear combinations affect speed and pedaling effort. By selecting your cassette and chainring, and entering your cadence, you can see how each gear will perform on the road. This is essential for optimizing your bike for climbing, sprinting, or endurance riding.

What Does Gear Ratio Mean?

The gear ratio is the number you get by dividing the number of teeth on your chainring by the number of teeth on your rear cog. For example, a ratio of 4.55 means that for every full turn of the pedals, your rear wheel turns 4.55 times. Higher ratios (like 4.55) are harder to pedal but make you go faster—great for sprints or flat roads. Lower ratios are easier to pedal and better for climbing hills. Cyclists use gear ratios to choose the best gear for their terrain, riding style, and fitness level.
