Our tools for cyclists

At Gravel Passion, we develop several free tools to help cyclists better plan their rides, optimize their gear and make the right decisions. Whether you ride gravel, road or MTB, these calculators and simulators let you quickly get the information you need.

Discover our main bike tools below, designed to be simple to use and available for free.

Pressure calculator

Size calculator

BAR to PSI Converter

Bike size simulator

Choosing the right bike size is essential to ride comfortably and avoid pain. Our bike size simulator lets you estimate the ideal frame size based on your body measurements and your discipline.

In just a few seconds, you get a tailored recommendation to guide you toward a gravel, road or MTB bike in the right size.

👉 Ideal for:

choosing your first bike
checking the size of a future purchase
comparing recommendations across brands

Tire pressure calculator

Tire pressure directly affects comfort, grip and efficiency. Our bike tire pressure calculator helps you determine the ideal pressure based on several factors:

your weight
tire width
terrain type
discipline (gravel, road…)

This tool is especially useful for gravel riders, where finding the right pressure can completely change the bike’s handling.

PSI / bar converter

Tire pressures are sometimes given in PSI, sometimes in bar, which can quickly get confusing. Our PSI / bar converter lets you instantly convert values so you can set your tires precisely.

A small, simple but very handy tool to avoid setup mistakes.
