Can I use this calculator with non-standard wheel sizes?

Yes, the tool allows you to enter a custom wheel size if the preset options do not match your bike's setup.

Does the calculator suggest the exact chainring and sprocket teeth I need to buy?

It provides gear ratio combinations; you will need to match those ratios to available chainring and sprocket sizes from manufacturers.

Is the tool accurate for both road and mountain bikes?

It supports common road and mountain wheel sizes, but accuracy depends on using the correct wheel diameter for your specific bike.

Do I need to create an account to use the Gearing Calculator?

No, the calculator is accessible directly online without mandatory paid access or account creation.

About this tool

What Bike Cadence Calculator does

The Gearing Calculator on TrainerDay Cycling Calculators helps cyclists identify suitable chainring and sprocket combinations to match a target speed and cadence. Users enter their desired speed, preferred cadence, and wheel size, and the tool returns a list of gear ratios that achieve those parameters. The interface offers both metric and imperial unit options and includes preset wheel-size choices such as 700c road, 29" mountain, and 27.5" (650b mountain) to simplify data entry. Results display gear combinations rather than raw calculations, making it easy to select compatible components. Unlike some competitors that focus on cadence-to-speed conversion, this tool is designed specifically to match gearing to a rider's target performance settings.

Step by step

How to use the TrainerDay Cycling Calculators Bike Cadence Calculator

1
Select your target speed and cadence using the input fields
2
Choose your wheel size from the preset options or enter a custom size
