Gates Centertrack

The belt has a groove cut down the center called the "Centertrack" so it cannot slide off the sprocket or chainring.

Gates makes two models of Centertrack belts called CDX and CDN.

CDX:
No lube required = no grease stains. Sheds dirt and grime, and cleaning with water is easy. Just get on it and ride. No chain = no chain clatter. It’s spooky quiet. A Gates Carbon Drive System weighs less than a chain. Lighter weight means higher performance. A very wide operating temperature range of 185F to -65F or 85C to -53C.

CDN:
Gates has specially engineered a new high modulus polymer belt with no-stretch carbon fiber tensile cords, and has developed a high-strength reinforced composite sprocket with CenterTrack™ design. Together, the new Carbon Drive™ CDN™ System delivers the reduced weight and optimal performance you count on from Gates, as well as new belt drive opportunities for your higher-volume models. CDN belts a recommended operating temperature of 140F ro -4F or 60C to -20C.
