Sram: INTEGRITY Eagle Technology creates the smoothest, quietest, longest lasting and most efficient drivetrains wave ever made. The radical new look and feel of our X-SYNC 2 Eagle chaining is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC chain rings. The longer, positive-rake tooth shape has been designed to work perfectly with the new Eagle chain to increase chain retention and overall pedalling efficiency, while decreasing friction, noise and wear. THINGS TO REMEMBER Only Eagle drivetrains are system engineered to give every rider the ultimate 1x experience.
