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.

Our fresh new updates include

Tioga FASTR
20 x 1.75 & 20 x 1.85
Tioga FASTR React
20 x 1.60 & 20 x 1.75
Tioga FASTR X
20 x 1.60, 20 x 1.75 & 20 x 1.85

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

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