TheKMC X11-SL DLC Chain is one of the lightest chains in its class - the Pro's choice. At 243g it's amongst the lightest chains in its class and, unlike others, is coated in DLC (Diamond Like coating) to reduce abrasive wear. Its surface hardness is greater than most coatings and this ensures its long-term functionality, optical stability and higher wear resistance. Triple X Durability also helps gives you unmatched chain life. At 116 links long with great mud shedding properties, this chain is as well suited for 29" MTBs as it is for road bikes.
