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 pedaling efficiency, while decreasing friction, noise, and wear. - X-SYNC 2 chainring design increases chain retention, wear life, and reduces friction and noise. - Designed to be used with Eagle chain - Boost 3mm offset

Shimano Ultegra R8000 Series Chainrings are designed for use with Shimano's 11-speed Ultegra crankset.

TruVativ XX Short Pin Chainrings for BB30 Cranks, use with 26T - Ring Position/Type: Inner - Drivetrain Speeds: 10 - Chainring BCD: 120 - Material: Aluminum

Intense study of chain and chainring wear patterns led to the radical tooth profile that lasts longer, runs quieter and further improves chain retention. - Can be used with Eagle 12 speed or SRAM 11 speed chains - Direct mount rings with 3mm offset fit Boost geometry Eagle cranks; direct mount rings with 6mm offset fit traditional geometry Eagle cranks and GXP spindle XX1, X01, X0, X1 and X9 cranks
