KMC X12 Chain - 12-Speed, 126 Links, Gold is a new, shop-stock drivetrain component for riders and mechanics maintaining 12-speed drivetrains. It is listed from our inventory data under KMC manufacturer reference CN12303 and UPC 766759712303.

Choose chain parts by drivetrain speed and the chain manufacturer's stated compatibility; parts that look similar are not automatically interchangeable across speeds or chain families. For a complete chain, confirm the required speed, link count, and any drivetrain-specific design before installation.

This product is sold as the package described in the title. Installation may require a chain tool and master-link pliers. Chain length should be sized to the bicycle rather than assumed from the package length. After installation, check articulation at the joined link, shift through every gear under light load, and verify that the chain runs cleanly without binding or derailleur interference.

If you are unsure whether this item fits your bicycle, bring the bike or the existing chain information to Acadiana Bicycle Company. We can confirm speed and compatibility, size a new chain, inspect cassette and chainring wear, and install the part.
