The drivetrain engineers at Sram have taken their research on the performance and longevity of thousands of X-Sync chainrings to offer even better chain retention with the X-SYNC 2 12-Speed Chainring. Pairing the aluminum X-Sync 2 with the groundbreaking Eagle drivetrain is a no-brainer for outstanding performance. The aggressive profile of the X-Sync 2 features boxier teeth that will hold your chain firmly in place allowing it to glide smoothly onto the cassette. The 6mm offset is ideal for chainlines with standard hubs. The X-Sync 2 is available in 30t 32t 34t 36t and 38t with a 6mm offset and in Polar Grey. Available with a 3mm Boost offset the chainring comes in sizes 30t 32t 34t 36t and 38t also in Polar Grey. If your frame doesn’t accommodate direct-mount chainrings or you simply prefer a four-bolt design this chainring’s four-104mm bolt construction still enables you to upgrade to Eagle.
