Sram:

THE NEXT EVOLUTION OF X-SYNC TECHNOLOGY
The radical new look and feel of the X-SYNC 2 chainring is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC chainrings. The aggressive tooth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC 2 design reduces friction and the accumulation of mud, grit and grime.

THINGS TO REMEMBER
Compatible with 11- and 12-speed drivetrains.
Designed specifically for Eagle chains and drivetrains.
X-SYNC 2 design increases chain retention and wear life, and reduces friction and noise.
