Description and Operation
 

Drive Belt

Proper belt tension is essential for optimum operation of the Gates Carbon Drive System. Lack of belt tension can lead to so-called “ratcheting.“ The teeth of the belt will slide over the teeth of the rear sprocket. This causes not only an unpleasant sound; the ratcheting can also cause damage to the carbon tensile cords. This would render a belt useless. If ratcheting has occurred you should replace the belt before the next time it is to be used. Too much tension can also cause damage to the bearings within the rear hub. It also increases the wear of your drive system and the system can drag.

The belt should be replaced at 37,000 km (24,000 miles).

Drive belt and sprockets do not need lubrication of any kind. For cleaning, use only water and a soft brush. Do not use any type of detergent. Proper handling of the belt is crucial to obtain maximum life expectancy. Bending or twisting of the belt may cause damage to the carbon fibers inside the belt. Avoid the following conditions when handling the belt.
