What Our Gearhead® Experts Are Saying:
"If you're building up a dream bike or chasing grams on race day, the XG-1299 is a no-brainer. It's impressively light, shifts smoother than anything else in the Eagle lineup, and the Ti Nitride finish adds just the right amount of flash and function."
The SRAM XG-1299 XX1 Eagle 12-Speed Cassette is engineered for riders who demand the best from their drivetrain. Built for Eagle setups and compatible exclusively with XD drivers, this high-end cassette features a 500–520% gear range that excels on both brutal climbs and fast-flowing descents.
CNC-machined from a single block of hardened steel, the X-Dome construction delivers SRAM’s best strength-to-weight ratio and exceptional durability. A Ti Nitride finish not only looks sharp but also sheds mud and keeps shifts clean and quiet in all conditions. Whether you're chasing podiums or just love top-tier performance, this cassette is the gold standard.
