Technology:

Gates Carbon Drive System
The main advantages of the Gates Carbon Drive system are cleanliness, smoothness and robustness. 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.

Gates CDN S150 ist bei mir nach einigen Jahren gebrochen, habe jetzt Gates CDN S250, das scheint mir von den Specs identisch zu sein, ist aber auf der Innenseite der Kurbel dicker und etwas schwerer, sollte also etwas stabiler sein. Gates bietet auch eine CDX Variante an, die wohl noch etwas stabiler sein soll, die ist aber nicht verfügbar.
