For over a decade we have been committed to providing the best and most comprehensive FREE online BMX Gear Calculator available.

While all other gear calculators provide you with the Gear Inches for your specific gear ours provides an accurate chart based on your tire of choice so you can compare other gear options with only one gear selection.

We got the call from a Gear Calculator user to add the Vee Rubber Speed Booster tires, so it was time for an update.

An evolution in racing competition. Speed Booster is designed for top BMX racers who demands lighter weight, better cornering stability and the lowest possible rolling resistance in high speed and grippy race courses. Thanks to our newly developed LSG+ compound, used exclusively for Speed Booster all of this is possible. The Speed Booster is designed just for you. The world’s fastest BMX racer.

We do plan to update the iPhone/iPad app soon to bring it in alignment with the online calculator.

The free web based online calculator works well on any browser and device (Android devices, iPhones, iPads, PCs, laptops, etc) and we encourage everyone to take full advantage of the free calculator.
