SRAM X-Sync 2 Eagle Chainring Direct MountThe radical new look and feel of SRAM’s 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. They 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 drivetrain’s 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 pedalling 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 aluminium Finish: Anodised Dimensions: BOOST or 49mm chain line Compatibility: Eagle or SRAM 11-speedTechnologies:X-Sync 2: X-SYNC 2 Eagle is the next evolution of SRAM X-SYNC 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 Eagle design reduces friction and the accumulation of mud, grit and grime.Buy SRAM Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
