The DLC12 is KMC's top-tier 12-speed chain, coated with a diamond-like-carbon (DLC) finish for the hardest, lowest-friction surface in the range.

  • DLC (diamond-like-carbon) coating over a titanium-nitride-plated, polished and heat-treated chain
  • Hollow inner and outer plates for reduced weight without giving up strength
  • 126 links
  • The hardest, lowest-friction surface finish in KMC's chain line-up

The DLC coating process — nickel plating, polishing, heat treatment, then the DLC surface itself — is what sets this apart from KMC's standard and lightweight chains, aimed at riders chasing the lowest drivetrain friction available.

Compatible with Shimano and SRAM 12-speed drivetrains (standard, not SRAM Flattop — see the X-FLATW range for AXS/T-Type).

KMC chains are covered against manufacturing defects. If a chain fails from a defect in materials or workmanship, return it to Tune Cycles with your proof of purchase and we'll manage the claim with KMC on your behalf — no need to contact the distributor yourself. This is in addition to your rights under Australian Consumer Law, which apply regardless of any manufacturer's warranty.
