The X11SL Silver is identical in every way to KMC's top of the line X11SL Gold chain, with the obvious exception of the gold Ti-Nitride coating. The X11Sl uses Nickel instead, which frankly gets the job done perfectly well. This fantastic chain is designed 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.
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 world's best bicycle chains producers.
The X11SL Silver chain is compatible with Shimano, SRAM and Campagnolo 11 speed drivetrains.
Less expensive than Campagnolo, excellent performance on both Chorus and Record groups, you can't go wrong.
Pros: light, less expensive but not cheap
