The sram eagle x sync direct mount chainring 30t the radical new look and feel of our x sync eagle chainring is a direct result of sram drivetrain engineers studying the performance and wear characteristics of thousands of x synctrade chainrings we subjected every size of chainring to untold environmental and mechanical tortures abuse and neglect in both lab and real world settings to come up with a chainring that would augment the eagletrade drivetrainrsquos performance in all c
