The chain is the heart of the Eagle drive train, completely re-engineered for 1x systems and the innovative X-Sync 2 chainrings. It offers longer wear with less friction and less noise than previous SRAM chains. Flowlink design eliminates square edges on outer plates to reduce friction and wearRecessed chain rivet contact area allows ultra-high joining strength with zero pin protrusionPowerLock non-reusable connecting link is includedTitanium Nitride surface treatment reduces friction and enhances wear FEATURES Unique design features provide significantly improved wear resistance.All-new Eagle Colorsystem facilitates dream-build curation.Designed and manufactured in our European facilities, it’s the quietest, strongest and most wear-resistant chain in the world.
