SRAM has pushed the boundaries of innovation by creating the lightest and most durable chain they've ever produced, while making it even lighter. This achievement was achieved without compromising on performance. The HollowPin construction, which replaces solid pins, is both lighter and stronger, while precision cutouts in the outer and inner plates have shaved off 13 grams compared to the previous generation. This results in a chain that is not only lighter, faster, and stronger, but also more durable." Features: - Flattop technology enables a narrower chain with quieter operation and increased strength and durability - Hard Chrome plated inner link plates and rollers for reduced wear and prolonged life. - HollowPin construction for increased strength and efficiency - Super-light outer plates with cut-out design. - 13 g lighter than previous RED chain Specifications: Compat - Speed (CN): 12s-Road Chain length (links): 114 links, 126 links Colour - Outer link: Rainbow, Silver Colour - Inner link: Rainbow, Silver Chain connector: PowerLock D1 Inner link finish: Chrome Plated/Chrome plated +PVD Outer link finish: Nickel/Nickel+PVD Pin variant: Hollow Pin Pin treatment: Chrome Hardened
