The strongest system is a chain with no weak links. Eagle chain links have a smooth radius with no sharp edges or chamfers, which yield a significant reduction in noise, friction, and wear. This design also allows for a flatter plate for more consistent chain riveting and greater overall strength. It's also the biggest contributor to the ultra-smooth, precise, durable, and quiet performance found in the 10-50T cassette and X-SYNC 2 chainrings. Additionally, installation is made easy with a dedicated 12-speed Eagle quick link. - Groundbreaking new chain design and technology - The Eagle chain has been completely re-engineered and is produced with new manufacturing technology. - All-new Eagle Power Lock chain connector with FLOWLINK technology provides better chain-guiding and increased longevity - The Eagle chain is the quietest, strongest, and most wear-resistant chain in the world - Unique features and design also provide significantly improved wear resistance on Eagle cassettes and rings
