The Eagle technology enables the smoothest, quietest, most durable, and most efficient drivetrain components we have ever built. The completely new design of the X-SYNC 2 chainrings is the direct result of research conducted by engineers who studied the performance and wear characteristics of thousands of X-SYNC chainrings. The longer, curved tooth shape works well with the current Eagle chains, ensuring good chain guidance and power transfer with less friction, noise, and wear. Offset with 32T without screws.
