bmxultra.com’s BMX Gear Calculator update
For over ten years 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 rollout 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 select your gearing options.
It’s been a long time coming but we’ve just added a lot of new tires. More sizes, more models, and more brands. Some of the new tires include the smaller Maxxis DTH tires (20 x 1 1/8″ and 20 x 1 3/8″), the new Arisun tires and the highly anticipated, and soon to be released, Alienation F1 and R1 TCS (tubeless) tires.
The iPhone/iPad app will be updated over the next couple of weeks to bring it in alignment with the online calculator.
An Android app is still on the cards but there is no ETA.
The free online calculator works well on any device and we encourage everyone to take full advantage of the free calculator.
