Ever heard of Titanium Carbon Nitride?

Neither had we until we read about the new KMC DLC series of Pro Racing chains. Boasting extreme surface smoothness and durability, the 4-stage coating and treatment process that each link goes through after the unique KMC shape forming and double X-bridge design includes heat treatment, surface treatment, NP plating and TiCN plating and is said to increase hardness by 300% and smoothness 10-fold. This makes for a chain that is lighter, stronger, smoother and harder, improving shifting, reducing friction and increasing durability and efficiency.

Apparently, it's the most widely requested chain by teams competing in the Tour de France, Vuelta a Espana, and Giro d’Italia. (yes, we know they're road races but the tech still applies to MTB)

Who's this item for: Riders wanting ultimate durability and maximum efficiency from a 12-speed chain, with crisp shifting performance.

Number of gears: The DLC 12 Pro Racing chain is suitable for 12-speed drivetrains from both Shimano and Sram as well as 12-speed drivetrains from other manufacturers.

Number of links: 126 Links making it suitable for a very wide range of bikes including some full-suspension e-bikes.

Weight: 260g

Quick joining link: Yes, included. Single-use only recommended.

Materials / construction: Links are formed from a special high alloy steel combination and then coated with a chemical surface treatment before NP plating and TiCN plating. Titanium Carbon Nitride coating technology from the Swiss watch industry provides the
perfect combination of metal and surface shield technology to upgrade plate hardness by over 300%. The inner and outer plates both feature chamfering and the outer plates use KMC's Double X-Bridge profile for wider compatibility and improved shifting and their pin technology makes KMC's chains the highest pin strength on the market.

Other component compatibility: Compatible with all 12-speed drivetrains. Can be used on E-Bike 12-speed drivetrains.
