Sram: integrityeagletechnology creates the smoothest, quietest, longest lasting and most efficient drivetrains weve ever made. The radical new look and feel of our x-sync2 eaglechainring is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of x-syncchainrings. The longer, positive-rake tooth shape has been designed to work perfectly with the new eaglechain to increase chain retention and overall pedalling efficiency, while decreasing friction, noise and wear.Things to rememberonly eagledrivetrains are system engineered to give every rider the ultimate 1x experience.the complete eaglesystemcrankset, chainring, chain, shifter, derailleur and cassetteis designed, tested and proven to deliver the ultimate mountain bike drivetrain.only eagleoffers the lightest, highest-performing, most durable system our engineers, professional athletes and customers asked for.only eagleis capable of revolutionizing t
