The SRAM XX1 Eagle chain (A3 generation) is a 12-speed Eagle chain built with hollow pins, hollow outer plates, and flat-chamfered side plates — delivering the lightest Eagle chain available, with smooth-radius engagement for fast, efficient shifting. The A3 revision refines the production tolerances and surface finish over prior iterations.

Highlights

  • 12-speed Eagle chain — A3 generation, top-tier XX1 construction
  • Hollow pins and outer plates for minimum weight
  • Flat-chamfered plates for smooth-radius cassette and chainring engagement
  • Includes PowerLock quick-link for tool-free connection
  • Compatible with all SRAM Eagle 12-speed drivetrains

Fit and compatibility
