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

The SRAM XG-1299 Eagle is a top-tier 12-speed MTB cassette built for riders who want a true 10-52T spread without giving up crisp shifting under load. With a massive 520% gear range on an XD driver, it supports faster gearing choices up front while keeping a low enough bailout gear for steep climbs—ideal for modern trail and XC race setups. Finished in Gold (C1), it delivers a distinctive look on high-end builds.

Dialed advantages for 10-52T Eagle drivetrains

1. 10-52T / 520% range - Expands both climbing and top-end options, reducing the need to compromise chainring size for the terrain
2. X-Dome architecture - Hollow, CNC-machined single-block steel design targets high stiffness and durability while keeping weight in check for race-focused builds
3. XD driver interface - Enables the 10-tooth smallest cog for higher top speed and a secure, proven cassette-to-driver connection
4. Mud-shedding open structure - Helps maintain consistent shifting performance in wet, gritty conditions by clearing debris more effectively
5. SRAM Eagle 12-speed compatibility - Direct fit for XD-equipped wheels; designed for Eagle 12-speed systems using a 10-52-capable rear derailleur
