The Sram Eagle Direct Mount 12-speed are provided with the X-Sync 2 technology. This is the name for SRAM's new version of the narrow-wide tooth profile. The teeth are higher and provided with chamfers in all directions. This way the chain should be more quieter and reduce the friction. Parallel to the optimisation of the profile of the front chain rings, SRAM also improved the chain, with the same intention: to be quieter. The inner rings are rounded off, there are no sharp bits. This way there is more room and it makes the process easier.
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. We 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 pedaling efficiency, while decreasing friction, noise and wear.
X-SYNC™ 2 chainring design increases chain retention, wear life, and reduces friction and noise.
