Whether you are an urban commuter, mountain biker, e-bike user or recreational rider, Gates Carbon Drive has a solution to fit your needs. Liberate yourself from oily, rusty chains and join the Gates Carbon Drive Revolution.
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.
Long service life: Tests have shown that CDX Carbon Drive belts last twice as long as bicycle chains.
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.
