Breaking the Chain: Belts Bring New Benefits to Bicyclists

Polyurethane belts replace traditional metal roller chains

Bicycle chains are receiving a well-deserved upgrade, thanks to PMA member Gates Corporation. As featured in a recent New York Times article, polyurethane belt systems are all the rage among commuter and city bicyclists, who no longer have to bother with the burden of oiling and cleaning standard metal rolling chains.

Gates Corporation’s grease-free alternative belts are made of polyurethane and shot through with carbon cords, which increase tensile strength and resistance to weathering. On one side of the belt, a series of teeth work with metal pulleys to turn the belt as the pedals rotate.

The benefits of cast polyurethane belt systems extend beyond lower maintenance into greater durability and a quieter biking experience. Polyurethane belts last far longer than metal chains and are expected to grow immensely in popularity among bikers. They’re already included on models from top brands including Trek, Raleigh and Specialized Global.

The Gates Corporation, based in Denver, makes industrial and auto parts for a number of applications. The company has been developing bicycle belt systems since 2007. Its latest system, CenterTrack (available next year), expands its offerings in the growing bike commuter market.
