Light, Durable, & Silent — Introducing The SRAM X-Sync Eagle 3mm Offset Chainring

The SRAM Eagle Chainring uses X-Sync 2 technology for increased chain retention and better performance for SRAM's 12-speed 1x drivetrains.

Made from forged and machined aluminum, these direct mount chainrings feature an aggressive hooked-tooth profile that was designed after studying the wear of countless original generation X-Sync chainrings tested in a variety of lab and real-world conditions. The result is a chainring that not only keeps a better hold of the chain on rough terrain but also creates less friction for decreased noise and extended life.


  • X-Sync chainring design increases chain retention, wear life, and reduces friction and noise
  • Chainring BCD: SRAM GXP Direct Mount
  • Made of forged and machined aluminum
  • Compatible with SRAM 12-speed 1x drivetrains
  • Designed to be used with Eagle chain
  • 3mm Offset
