KMC X12 Chain - 12-Speed, 126 Links, Gold

The KMC X12 is a 12-speed bicycle chain at 1/2" x 11/128" width, compatible with Shimano, SRAM, and all other 12-speed drivetrains in 1x12 and 2x12 configurations. The 126-link Ti-N gold finish adds a titanium nitride coating for surface hardness and corrosion resistance over extended use. KMC's asymmetrical chamfering on the inner and outer plates guides chain-ring engagement under load to sharpen shift response. A CL552 Missing Link connecting link is included. The X12 works across road, gravel, cyclocross, and mountain applications wherever a standard 12-speed chain is specified.
