SRAM X-Sync 2 SL Eagle Boost Chainring Direct Mount 12-speed lunar grey

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 
X-SYNC 2 Eagle is the next evolution of Sram X-SYNC technology. The aggressive teeth design provides better chain retention fpr smoother, mor efficient pedal feel. Whith a focus on long-life, the X-SYNC 2 Eagle design reduces friction and the accumulation of mud, grit and grime.
