Thats right - the Connex 11s0 chain works perfectly with all 11-speed Shimano, SRAM, and Campagnolo systems.
The 11s0 also works perfectly on 1x11 set-ups and shifts even more quietly than some system-specific chains.
-"The Connex 11s0 worked flawlessly for 700 miles of riding — mostly cyclocross, including 14 races. The shifting was on par with any Shimano, KMC, or SRAM chain we’ve used before." -Spencer Powlison, VeloNews. Read the full review at Velonews.com.
- Michael Hotten of RedKitePrayer.com replaced a Shimano DA 9000 chain with a Connex 11s0. "The Connex moves between cogs no faster than the 9000. What it does offer is a more positive feel. The German chain responds to rear derailleur movements with a “click” as it moves to a new cog. If you are all into that buttery, Shimano feel, this may not be a plus. But in rough conditions or during hard efforts, I appreciated getting the feedback." Read this great review from RedKitePrayer.com.
- Dan Empfieldof Slowtwitch.com calls it "the equal of Shimano's Dura-Ace chain." Read the Slowtwitch.com review.
