Intense study of chain and chainring wear patterns led to the radical tooth profile that lasts longer, runs quieter and further improves chain retention. Oval ring shape for riders that want to adjust the power profile of their pedal stroke. - The only oval rings with X-Sync 2 tooth design - Direct Mount Type: Direct Mount SRAM - Drivetrain Speeds: 10, 11, 12 - Material: Aluminum - Ring Position/Type: Chain Retaining Single Ring - Round or Oval: Oval - Chainline/Hub Compatibility: 141/148 Boost Hubs

It’s undeniable that some riders’ pedaling styles benefit from oval chainrings, so SRAM has engineered the new X-SYNC 2 Oval chainrings to give them the advantage they want. They are the only oval option available with SRAM's genuine X-SYNC 2 teeth profile, so they are the only oval chainrings on the market that are 100-percent optimized for Eagle. - Direct Mount Type: Direct Mount SRAM - Drivetrain Speeds: 10, 11, 12 - Material: Aluminum - Ring Position/Type: Chain Retaining Single Ring - Chainline/Hub Compatibility: 135/142 MTB Hubs, 150/157 DH Hubs, 170/177 Hubs

Eagle Technology creates the smoothest, quietest, longest lasting and most efficient drivetrains SRAM has ever made. The radical new look and feel of the 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 Eagle chains to increase chain retention and overall pedaling efficiency, while decreasing friction, noise, and wear. The complete Eagle system—crankset, chainring, chain, shifter, derailleur and cassette—is designed, tested, and proven to deliver the ultimate mountain bike drivetrain. Put simply, Eagle is capable of revolutionizing the ride for all riders on every kind of terrain. - Designed to be used with Eagle chains - Material: Aluminum
