Urban commuters as well as mountain bikers, e-bike users or leisure riders benefit from the high mileage. Oil-stained or rusty chains are a thing of the past. Clean: No lubricant means no accumulation of grease and dirt. Smooth and silent operation: no metal-to-metal contact of the chains. Light: The whole system weighs less than a standard bicycle chain. No elongation: Belt does not need to be re-tensioned or replaced. Self-cleaning: CenterTrack and MudPort profiles are specially designed to repel mud, dirt, snow or other contaminants. Consistent efficiency: The drive boasts a long service life compared to that of a conventional chain, where efficiency is significantly reduced by wear or dirt. Installing a Gates Carbon Drive Belt Drive requires a specially-made frame, therefore we strongly advise against using one to modify a conventional framework.
