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.
