Is Bike Gear Calculator free to use without creating an account?

Yes, the tool is available online for free without a paid plan or mandatory account registration.

Can I compare multiple chainring and sprocket combinations at once?

The tool generates gearing tables based on the selected chainring and sprocket inputs, allowing users to view ratio combinations for their chosen setup.

Does the calculator account for wheel and tire size?

Yes, users can optionally input wheel diameter or tire size so that speed and cadence values reflect their actual bike configuration.

How does this calculator differ from Sheldon Brown's gear calculator?

This version offers a simpler, free interface focused on basic chainring and sprocket ratio analysis, whereas Sheldon Brown's tool includes support for internal hubs and more extensive customization options.

About this tool

What Bike Gear Calculator does

Bike Gear Calculator is a free online tool on Ritzelrechner.de for analyzing bicycle drivetrain ratios. Users enter chainring and sprocket teeth counts to generate gear ratios, gear inches, and speed/cadence tables. The site also accepts wheel and tire parameters, allowing results to reflect the rider's actual setup rather than generic defaults. Compared to other bike gear calculators, this version distinguishes itself through its integration within the Ritzelrechner platform, offering a straightforward interface focused on ratio analysis without the additional features or hub-complexity found on sites like Sheldon Brown, while still providing the core gearing tables and cadence views that cyclists need for drivetrain setup.

Step by step

How to use the Ritzelrechner Bike Gear Calculator

1
Select your chainring teeth count from the chainring input
2
Enter your sprocket/cog teeth count from the sprocket input
3
Optionally input your wheel diameter or tire size for realistic speed/cadence values
4
View the generated gearing table showing ratios, gear inches, and speed at given cadence

Is it right for you

Best for

Cyclists and bike builders who want a free, no-frills way to compare chainring and sprocket combinations and see how wheel size affects gear inches and speed.

Limitations

No explicit mention of unit switching between inches and millimeters
Results depend on user-entered wheel/tire data for realism
Interface is basic and lacks advanced hub or motor-specific calculations
