Eagle Technology creates the smoothest, quietest, longest lasting and most efficient drivetrains we’ve ever made. The radical new look and feel of our X-SYNC 2 Eagle chainring is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC chainrings. 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. Designed to be used with SRAM eagle 12 speed drivetrains 30, 32 and 34T available Direct mount 3mm offset, boost spacing X-Sync design increases chain retention, chain wear and pedalling efficiency Cold forged aluminium
