The XG-1299 cassette delivers top-tier performance with a wide 520 percent 10-52T gear range, allowing more speed without losing climbing efficiency. Built with SRAM’s strongest X-DOME design and the proven XD driver, it offers excellent power transfer, durability, and broad Eagle compatibility. Premium finishes make it a perfect match for high-end race and custom builds.

Technology

• XD DRIVER BODY
  XD is a cassette driver body design that allows the use of a 10-tooth small cog and provides an improved interface with the cassette.
  
• X-DOME
  X-DOME technology creates an incredibly lightweight, precise and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.
  
• Eagle
  Eagle technology represents our newest 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 520%, which is equal to 2x11 drivetrains.
  
• X-GLIDE 2
  X-GLIDE 2 is next generation of SRAM X-GLIDE technology optimized for the EAGLE 12-speed cassette. It provides quick, precise, power-on shifting performance throughout the gear range, and increases chain retention on larger cogs.
