This chain features 118 links and is manufactured by EK, a trusted name in drivetrain components. Manufacturer and vendor part number 520SRO6-118 identifies this specific chain configuration for accurate ordering and replacement.
Built from high-tech, heat-treated steel alloy, the EK 520 SRO6 chain provides dependable strength and durability for everyday riding and demanding use.
