SRAM GX Eagle XG-1275 12-Speed Mountain Bike Cassette

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. 

FULL PIN technology uses eleven lightweight, stamped cogs held together with 123 high-strength stainless steel pins. The result: a cassette that's light, durable and equipped with SRAM's super wide 10-42 gear range that's a perfect fit for any ride. The open design similar to our X-DOME cassette aids in mud clearance, giving you cleaner shifting performance and longer component life.

Eagle technology represents our newest lx drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new lx 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.

• 520-percent gear range utilizing the industry standard XD™ hub driver. 
• Light and strong FULL PIN™ technology similar to X-DOME™ bringing true 1x gear range to more riders and builds. 
• Lunar and black colorway makes the XG-1275 cassette right at home on any build.
