Gates Carbon Drive

Tools for a Smooth Ride

Proper belt tension is important. Too little tension can lead to tooth jump or "skipping." Too much tension can cause wear and damage. Here are several tools to ensure the best tension and the smoothest ride. 

Gates Carbon Drive™ Mobile App

Gates Carbon Drive is the high-tech belt drive for bicycles, motorcycles, & scooters. This app measures belt tension sonically. Just pluck your belt like a guitar string and use the microphone on your phone to read the vibration frequency. Compare your bicycle belt’s frequency to the included chart to see if you need to adjust the tension. For scooter/motorcycle tension recommendations, compare to your vehicle owner’s manual.

Strap Wrench

Designed for quick, easy removal of your rear sprocket, Gates Strap Wrench is similar to a chain whip and holds the cog securely in place for easy removal of the cassette lockring. Equipped with a reinforced strap and an anodized alloy handle, this wrench is strong and easy to grip—and a must-have for any bike mechanic or bike shop owner. To prevent damage, never use a Carbon Drive belt as a chain whip.
