By cold-forging pin collars to encase the thermally refined alloy steel chromium carbide layered pins, outer chain plate thickness can be slimmed to reduce weight while increasing tensile strength. Featuring Slim O-Ring Technology, which offers superior, long lasting chain lubrication in a slimmer profile, eliminating the clearance issues of competing O-ring chain designs. The result is slim, ultra-premium, light weight racing chains with unparalleled strength and prolonged lubrication over the competition.\n\u003cul\u003e\n  \u003cli\u003eEngineered for maximum strength, durability, and smooth power transfer in demanding off-road and racing conditions\u003c\/li\u003e\n  \u003cli\u003eBuilt from premium materials with precision manufacturing to deliver long-lasting performance and reliability\u003c\/li\u003e\n  \u003cli\u003eLightweight design reduces friction and rotational mass for improved throttle response and acceleration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe ProTaper Pro Series Forged 520 Slim O-Ring Chain Link is designed for demanding off-road and racing conditions.
