Eagle technology creates the smoothest, quietest, longest-lasting, and most efficient drivetrains we've ever made. The radical look and feel of our X-SYNC 2 Eagle chainring is the direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC chainrings. The longer, positively raked tooth shape was designed to work seamlessly with the new Eagle chain to increase chain retention and overall pedaling efficiency, while reducing friction, noise, and wear.

Technology

X-Sync 2
X-Sync 2 Eagle technology is the evolution of the previous X-Sync. The aggressive tooth design ensures better chain retention for a smoother and more efficient pedaling. Particular attention has been paid to the chainring's longevity; X-Sync Eagle technology reduces friction and the accumulation of mud, sand, and dirt on the chainring.
