Sram: The all-new SRAM RED chain was redeveloped from the ground up. The unique link shape allows the chain to be narrower and lighter while increasing strength and providing more space between the outer plates of the chain and the cogs on either side. Result: a quieter chain with faster, more precise shifts.FEATURESFlattop technology enables a narrower chain with quieter operation and increased strength and durabilityHard Chrome plated inner link plates and rollers for reduced wear and prolonged life.HollowPin construction for increased strength and efficiencyRequires new Flattop Powerlock SPECIFICATIONSCompat - Speed (CN): 12s-RoadChain length (links): 120 linksColor - Outer link: SilverColor - Inner link: RainbowChain connector: PowerLock D1Inner link finish: Chrome PlatedOuter link finish: NickelPin variant: Hollow PinPin treatment: Chrome Hardened
