Think precision. Think performance.

You'll agree that CDS is to bikes what HD is to TV. Once your customers discover the difference, there's no going back. It's a great opportunity for you to offer a greaseless belt drive system to a wide audience, whether it's the non-traditional bike rider who is looking for an alternative to cars on short errands or the well-versed mountain biker looking for system improvements.



Split Bike Frame

A belt drive requires a split or opening in the frame. This design varies by manufacturer.


CarbondriveSystem Calculator

This calculator is used to find the closest stock combination of sprockets and belts that achieve the same gear ratio of an existing (or designed) drive on a bicycle. It also does a few calculations that are of interest to bike builders (gear inches, development, and gain ratio) for the selected solution.
