KMC X11SL SuperLight 11Speed

The Lightweight Speed Link.

The KMC X11SL stands out because of its Hollow Plate and Hollow Pin construction. By strategically milling out the inner and outer plates and using hollowed-out rivets, KMC has achieved a weight that rivals or beats almost any other 11Speed chain on the market. Despite its skeletal appearance, the Double X-Bridge outer plate design ensures that shifting remains crisp and reliable across all 11Speed drivetrains, including Shimano, Sram, and Campagnolo.

Why the X11SL is the Weight-Weenie's Choice:

• Super Light Construction: Features laser-cut hollow outer and inner plates along with hollow pins, bringing the weight down to approximately 231g significantly lighter than standard high-end chains.

• Double X-Bridge Technology: The outer plates feature unique chamfered angles that allow for faster and smoother gear transitions, even under high pedaling loads.

• Ti-N (Titanium Nitride) Coating: Available in a striking gold finish, the Ti-N coating isn't just for looks; it provides a harder surface that reduces friction and extends the wear life of the chain.

• Non-Directional Design: Unlike many 11Speed chains, the X11SL can be installed in either direction, making setup simpler and reducing the risk of a "backwards" installation.

• Universal 11Speed Compatibility: Works flawlessly with Shimano, Sram, and Campagnolo 11Speed drivetrains, making it an incredibly versatile upgrade or replacement.

• MissingLink Included: Every chain ships with a high-quality CL555 MissingLink, allowing for tool-free assembly and easy removal for deep cleaning.

The Alegro Perspective: In the shop, we use the X11SL when a customer says "make it as light as possible." It’s one of the few places where you can save ~20-30g without any real downside in performance. The gold version is also a classic way to add some "bling" to a blacked-out bike. While it’s slightly more expensive than a standard chain, the combination of low weight and KMC’s legendary durability makes it a worthwhile investment for a high-end build.
