Gates Carbon Drive is the high tech belt drive offering for bicycles. This app is designed to help your bike find its true belt drive potential.
Interested in key parameters of your drive like speed ratio or center distance? Want to know what belt lengths or sprocket sizes will fit your ride? What about comparing one bike to another to tweak your ratio perfectly? With our calculator and catalog, you can stay on top of the perfect setup for your drive.
What about tension? Is my tension too high or too low? Don’t have a proper tool? Well now we’re putting one of the easiest and best tension tools right into your iPhone (or iPod touch with microphone – not included). Just pluck your belt like a guitar string, and use the microphone on your iPhone to read the frequency that it’s vibrating at. Compare your belts frequency to the included chart to see if you need to adjust the tension.
