The radical new look and feel of Srams X-Sync™ 2 Eagle™ chainring is a direct result of the study of performance by the Sram engineers. Also wear characteristics of thousands of X-SYNC™ chainrings are studied. Sram subjected every chainring size to untold environmental and mechanical tortures,abuse and neglect, in the lab and in the real world, to come up with a chainring that would augment the Eagle™ drivetrain’s performance in all conditions.The longer, positive-rake tooth shape is designed to work perfectly with the new Sram Eagle™ chain, to increase chain retention and overall pedaling efficiency, while decreasing friction, noise and wear.Features:- The X-Sync™ 2 chainring design increases chain retention,wear life, and reduces friction and noise- Designed to use with the Sram Eagle™ chainSpecifications:- Sram GX Eagle chainring- Material: Forged and machined aluminum- Compatibility: Sram Eagle™ or Sram 12-Speed- Type: GXP Direct Mount- Teeth: 30T- Dimensions: 49 mm chain line- Size/BCD: Sram Direct Mount- Finish: AnodizedCranks Compatible: - Sram GX 1400 GXP - Sram GX Eagle GXP - Sram GX Eagle BB30 - Sram X0 GXP - Sram X0 BB30 long - Sram X1 GXP - Sram X9 GXP - Sram X9 BB30 long - Sram X01 GXP - Sram X01 Eagle GXP - Sram X01 Eagle BB30 - Sram XX1 GXP - Sram XX1 Eagle GXP - Sram XX1 Eagle BB30
