The versatile KMC X12-Ti Gold chain is an easy upgrade to any SRAM 12-speed drive train. A special titanium nitride coating gives the X12 an extraordinarily long lifespan (potentially over 10,000 miles.) The unique Double "X" shape of the outer plates, with beveled edges, delivers precise and noiseless shifting. Includes KMC's proprietary "missing link" that offers quick and easy chain removal for cleaning or shortening.
