The KMC Chain Industrial Company's sole focus is to create the world's best chains by amalgamating proven construction methods with quality raw materials. They have a manufacturing campus in Tainan County, Taiwan where all product is produced in-house to control quality. Since the mid-80s KMC has had a partnership with Shimano. Chain making is a complex process and requires specialty facilities. Shimano chose KMC because they're simply one of the best at producing chains.

The X11SL Ti Nitride is KMC's top of the line offering to fit all Shimano, SRAM and Campagnolo 11 speed drivetrains. The chain is joined with KMC's Missing Link connector link. This greatly simplifies the installation process and also allows the user to remove the chain for cleaning and bike maintenance. The weight of this X11SL chain in the feathery 230 gram range. This is made possible from the inclusion of hollow pins and side plates. The inner and outer plates are chamfering to allow the chain to move from gear to gear precisely. The Double X Bridge shape outer plate helps to provide lightning fast shifts by improving stiffness of each link. Bushing-less construction helps give the chain what KMC refers to as noiseless function and our experience confirms this chain is one of the quietest we have ever worked with.

This chain gets its gold appearance thanks to its Titanium Nitride coating providing both amazing corrosion and stretch resistance. Good looks, excellent shifting, low noise and super easy installation definitely make it worth every penny.
