The radical new look and feel of SRAM's 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.

SRAM 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 2X-Sync 2 Eagle is the next evolution of SRAM X-Sync technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-Sync Eagle design reduces friction and the accumulation of mud, grit and grime.


X-Sync 2 chainring design increases chain retention, wear life, and reduces friction and noise.

SRAM XX1 Eagle | SRAM X01 | | March 2016

“We loved the fact that we could pedal(ride) faster on the downhills: with the 34-10 it’s easy to reach 40 km/h pedaling, and this can be an advantage when racing. Combined to the fact that the 50T cog allows to climb every steep trail in sight, the Eagle reaches the purpose of widening the reach of the single chainring drivetrains, even for those who felt the 1×11 was too short, both for racing and for recreational purpose.” View Article

SRAM XX1 & X01 Eagle - Pinkbike's first impressions

"The most immediate sensation was just how smooth the drivetrain felt. Sure, a brand new drivetrain will always feel better than one that's had the snot beat out of it for months, but this was something different. The interaction between the chain and chainring feels absolutely seamless, almost as if it were somehow one unit rather than two separate components." View Article

"SRAM Eagle 1x12 | The Front Derailleur Killer" -

With a highly positive and thorough feature on both XX1 Eagle™ and X01 Eagle™ they concluded - "With gear range out of the picture, there are now very few arguments left for not switching to a simpler, quieter, and easier-to-use 1X drivetrain... View Artcle

SRAM XX1 Eagle | First Ride -

"SRAM has trumpeted a host of non-gearing related improvements between its 1×11 and 1×12 drivetrains, it’s the gearing that will always draw the most now have a full 500% range, which on the bike feels a lot like what you get from a traditional 2x system, just with one less derailleur and shift lever."

"But when you add a 50-tooth cog to the equation, the front derailleur becomes obsolete, which forever minimizes cockpit clutter." View Artcle
