Sram X-SYNC 2™ Eagle™ Boost 11/12v 3mm Steel 30T Chainring
Eagle Technology creates the smoothest, quietest, longest-lasting and most efficient transmissions we've ever made. The radically new 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, positive rake tooth shape was designed to work seamlessly with the new Eagle chain to increase chain retention and overall pedaling efficiency, while decreasing friction, noise and wear.
