SRAM X-SYNC EAGLE Direct Mount Chainring, 3mm Offset 12 Speed, Black Gold

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. 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 Eagle drivetrainu2019s performance in all conditions. 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. Features : X-SYNC 2 chainring design increases chain retention, wear life, and reduces friction and noise. Designed to be used with Eagle chain Material : Forged and machined aluminum Compatibility : Eagle 12-speed Dimensions : BOOST or 49mm chain line SRAM direct mount Weight : (66g) 28 dents (68g) 30 dents (71g) 32 dents (76g) 34 dents (91g) 36 dents Technologies : X-SYNCu2122 2 Eagle is the next evolution of SRAM X-SYNCu2122 technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC EAGLEu2122 design reduces friction and the accumulation of mud, grit and grime.
