The KMC X12LW is a lightweight 12 speed chain that arrives pre-waxed with KMC GO wax, so it runs with low friction from the very first pedal stroke. It comes in a limited edition presentation box, in Aurora Blue or Titanium Nitride Gold.

Waxed chains stay cleaner than oiled chains and pick up less grit, which means less wear on your drivetrain and less time spent cleaning. Whether you are into road, gravel or mountain bike cycling, this is a premium upgrade or a standout gift for the cyclist who has everything.

Pre-waxed and ready to go

KMC treats the chain with its GO wax formula at the factory, so there is no messy lube needed before your first outing.

Light and efficient

Hollow pins keep the weight down to 223 grams per 110 links, for a chain that feels quick on the climbs.

Precise shifting

KMC’s Double X-Bridge design gives accurate, reliable gear changes across the cassette.

Limited edition presentation

The chain is supplied in a limited edition box, making it a great gift. The Gold version has a Titanium Nitride coating that is harder and more resistant to corrosion than a plain finish.
