Chain Super Record 12 Speed: Slim, robust, smooth, and precise. The seemingly simple chain is crucial and essential for the cyclist's safety and for optimal performance of the entire drivetrain system. The Super Record 12 Speed chain has been redesigned to facilitate integration with other components of the drivetrain system. The primary and fundamental goal was to reduce dimensions. Thanks to the pins that are perfectly flush with the outer surface of the links, the width is 5.15 mm. The second goal was to enhance performance with the Ultra-Link system, which improves the safety and lifespan of the chain, as well as a special treatment that significantly increases smoothness and shifting precision. Weight: 220 g. Pins flush with the outer surface. Ultra-Link system. Type: Chain. Material type: Steel. System compatibility: 12-speed. Number of links: 114.
