Lack of belt tension can lead to tooth jump or “skipping”, when the teeth of the belt slide over the teeth of the rear sprocket. Too much tension can damage bearings, can cause the system to drag, and can increase the wear of your drive system. There are 3 common methods for measuring tension on your Carbon Drive system: the Gates Krikit Tension Gauge, the Eco Tension Tester, and the Gates Carbon Drive Mobile App for iPhone and Android. For each of these, the tension may vary a little along the belt, so you should repeat this procedure several times. Rotate the cranks a quarter turn after each measurement and measure again.
More information about checking the belt tension can be found at the website of Gates.
Note: Your Carqon dealer can help you to check the right belt tenstion and adjust the belt tension for you, if needed.
