Gates CDX 3-cam SureFit Shimano Unified Rear Belt Drive Sprocket

This Gates CDX rear belt drive sprocket for touring use has three SureFit™ cams, fits the so-called Unified Beltline of 45.5 mm and is compatible with Shimano Alfine 8- and 11-speed mechanical and Nexus Disc 3-, 7- and 8-speed internally geared hubs. A belt line that is further out than on older models with 43.7 mm ensures higher performance, especially in combination with mid-drive motors.

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.
