Built to have us speeding by faster than an alien spaceship the CeramicSpeed UFO Chain KMC 12-speed has our drivetrain working more efficiently and faster than ever. Coated in a state-of-the-art ceramic material the chain saves additional watts when working through our drivetrain. Chains with this coating are painstakingly run through the CeramicSpeed factory and checked for ultimate efficiency, all so we can be confident going into our next road race event.
