Item # KMC0003


For years, cycling component manufacturers have been trying to reinvent the wheel. And the tire. And the shift-lever. And -- well, you get the point. So with all this innovation, it was only a matter of time before someone attempted to reinvent the chain. Enter the 228-gram KMC X11SL-CP, one of the lightest, smoothest, and most durable chains on the market.

Thanks to a bushingless construction that uses mushroomed rivets to combat stretching and fatigue, the X11SL-CP delivers strength and durability in a quiet package. Both inner and outer plates are chamfered for precise movement, while KMC's patented Double "X" Bridge shape on each outer plate further enhances the chain's ability to provide smooth shifts in all conditions.

Perhaps best of all, the KMC X11SL-CP comes with its own KMC Missing Link 11 -- itself a miracle product -- so you won't have to fuss with special pins or chain tools to install it. Light, durable, quiet, and smooth, the KMC X11SL-CP is specifically designed for 11-speed drivetrains, and conveniently works with Campagnolo, Shimano and SRAM.

Works great on my dura ace 11 speed

  • Familiarity: I've put it through the wringer

I used to run 10 speed kmc and it was a let down going back to shimano when I upgraded to 11 speed. The KMC shifts just as good if not better the the shimano chain, is quieter in general use and has cured the horrible sound the shimano chain made on the rear cassette during hard climbing efforts. The other advantage is you can remove the chain to properly clean the drive chain. I weight just under 190 and ride about 200 miles a week and uses Dumound lube.

Noisier, Not as Strong

I like to remove my chain to clean it thoroughly, so I thought I'd switch my Campy chain for a KMC 11SL, mainly for ease of removal/reinstallation, and a little weight reduction never hurt (claimed 228g @112 links). The cleaning I wanted was all well and good, but I was surprised to find, or, hear a noticeable difference. The KMC chain made a lot more noise, and was a lot less smooth, even after neurotic amounts derailleur adjustments. The Campy chain ran like butter.

Second, and more significant, the KMC chain has been the only chain in my 5 year road riding history (meager, I know, but still!) that has broken while on a ride. I weigh in at 145 pounds in the off season, and the only guys I witnessed break chains were 180+ pound, big legged sprinters. Not this time. I was, however, doing a seated, 5 second max power test on a 6% grade at the time of the break. Still, this is nowhere near the punishment my Campy chain had taken. I switched chains about 8 month ago, and the KMC has seen several thousand miles since then.

The point of breakage happened, not at the "missing link", but the outer plate of a regular link. The plate had separated from the pin during the initial break, then the chain fully broke loose and separated as I continued to pedal. No warranty for KMC chains. Boo.

Does this work with the new shimano 11...
