The radical 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. They 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 Eagle chain to increase chain retention and overall pedaling efficiency, while decreasing friction, noise and wear.

- New 3D composite chain ring teeth composition is optimized for chainwheel load out

FSA ATB chainrings deliver flawless shifting for any mountain drivetrain. Available in alloy and steel options.

SRAM's X-Sync 11-speed chainring features tall teeth with an alternating tooth profile to hold the chain amazingly well and still provide space for mud to clear. - Drivetrain Speeds: 10, 11 - Material: Aluminum - Ring Position/Type: Chain Retaining Single Ring

Intense study of chain and chainring wear patterns led to the radical tooth profile that lasts longer, runs quieter and further improves chain retention. - Can be used with Eagle 12 speed or SRAM 11 speed chains - Direct mount rings with 3mm offset fit Boost geometry Eagle cranks; direct mount rings with 6mm offset fit traditional geometry Eagle cranks and GXP spindle XX1, X01, X0, X1 and X9 cranks

Mud and moving parts are enemies in the sport of cyclocross. That's why SRAM decided they were going to simplify things. Remove the front derailleur, increase the range of the cassette, make dropped chains a thing of the past, and you've got a cross drivetrain worthy of hammering. SRAM's CX1 X-Sync Chain Ring is an integral part of that system. It mates to 110 BCD cranks and features a wide-narrow-wide tooth profile to securely hold the chain through the roughest terrain. It's also specially designed with mud clearing in mind to keep your rig light and fast. A variety of sizes ranging from the spin-to-win 38T to the flat-out 46T let you dial in your rig for your strengths or course.
