SRAM Eagle’s 12-Speed Mountain Bike Drivetrains

Since 2016, Eagle has emerged as a gold standard for mountain bike performance, allowing riders to truly shift without worry, even under maximum effort. Every SRAM Eagle groupset is engineered to handle all the power you can throw down, even on the toughest terrain. Transform your ride with the Eagle 12-speed drivetrain system, delivering an unprecedented 500%+ gear range with single chainring simplicity.

Discover the Eagle Ecosystem

The GX Eagle remains our most popular choice, balancing professional-grade performance at an accessible price point that works for most riders. For entry-level riders who aren’t so concerned about weight, NX Eagle and SX Eagle provide the same revolutionary 12-speed technology using more budget-friendly materials. Advanced or elite riders choose XX1 Eagle and X01 Eagle for unbeatable weight savings and precision engineered carbon construction.

Every Eagle system features the game-changing eagle 12 speed cassette 10-52, with a 520% gear range that allows for easier gear switching on climbs and descents. The SRAM Eagle derailleur, SRAM Eagle chain, and SRAM Eagle crankset work seamlessly together, while the Eagle cassette relies on SRAM's XD advanced driver technology for optimal gear progression.
