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 a chart so you can compare other gear options with only one gear selection. You can also use the chart itself to change to a preferred ratio select your gearing options, and save up to five selections to your browser.

We got the call from a Gear Calculator user that we still hadn’t added the Box and Driven tires, so it was time for an update.

Our fresh new updates include

Box

• Hex Lab Folding 20×1.75
• Hex Lab Folding 20×1.9

Driven

• System 2 Folding 20×1.75
• System Y Folding 26?

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.
