XG-1299 Eagle Cassette - 12-Speed, 10-52t, XD Driver, Rainbow, C1

The SRAM XG-1299 Eagle Cassette is a top-tier 12-speed MTB cassette built for riders who want maximum range without giving up crisp shifting under load. Its 10-52t spread delivers a true 520% gear range, letting stronger riders step up to a larger chainring for more top-end speed while still keeping a bailout climbing gear. The Rainbow finish adds a distinctive look to an all-business drivetrain component designed for XC, trail, and enduro use.

Upgrade-focused features that matter on the trail

1. 10-52t, 520% range - Expands gearing for steep climbs and fast descents, making it easier to tune cadence and chainring choice to the course or terrain
2. X-Dome architecture - Hollow, CNC-machined one-piece steel construction improves stiffness for precise shifts while keeping durability high for race and high-mileage use
3. XD driver interface - Required for the 10-tooth smallest cog, and a direct fit for wheels already running an XD freehub body
4. Mud-shedding cassette structure - Open design helps clear debris to support consistent shifting in wet or gritty conditions
5. SRAM Eagle 12-speed compatibility - Designed to pair with SRAM Eagle 12-speed drivetrains for clean indexing across the full cassette range
