Gates Carbon Drive has just announced their new CDN belt drive system as part of a value-oriented product line designed for urban bikes. The CDN uses the same carbon fiber tensile cord technology and Centertrack sprocket design as Gates’ CDX system, but it will sell for about half the price of the company’s higher end CDC/CDX models. CDN is essentially a lighter-duty iteration designed for low mileage city bikes in easy riding applications.
“CDN is our value-oriented belt drive for people who want a clean and stylish city bike for getting into town or around the neighborhood,” says Todd Sellden, director of Gates Carbon Drive. “It’s for bicyclists who ride in jeans or skirts and casual shoes, not spandex and race gear.”

Gates’ 12mm wide Centertrack belt features nine carbon fiber cords embedded inside a high-tech polyurethane belt that is engineered to be flexible, durable and resistant to UV rays. The CDN crank and front sprocket are both glass-reinforced composite units, and the rear sprocket is made of steel. The belts will be manufactured alongside Gates’ automotive belts in the company’s Scotland facility.
The CDN is a price-point system intended for city bikes that see light duty use like grocery/beer runs and relaxed urban riding. For those riding off road, racing cyclocross or bicycle touring, the CDX’s alloy debris shedding sprockets are your best bet in variable weather conditions. Gates’ CDC belts and sprockets are designed for performance commuter/pavement bikes and tandems.
A properly set up belt drive system offers a clean, low maintenance drivetrain that runs quiet, requires no grease, uses a belt that won’t stretch or rust, and according to Gates weighs less than a chain drive setup. The design’s simplicity makes sense for a low-maintenance single speed or internally geared townie bike, and by making it a more affordable option Gates hopes to see the masses go unchained.
Gates will be launching the CDN system at this year’s Taipei Bike Show, March 18-21st 2015.
