The History of SRAM Eagle™ Drivetrains
The SRAM Eagle™ drivetrain revolutionized mountain biking when it was first introduced in 2015, bringing wide-range 12-speed shifting to riders who previously needed multiple chainrings to achieve the same versatility. Before Eagle, most drivetrains were limited to 10 or 11 speeds, meaning riders often had to compromise between climbing efficiency and high-speed performance. SRAM Eagle changed that with a single-chainring setup paired with a 10-50t cassette, giving riders a 1x system that handles everything from steep climbs to fast descents with precision and reliability.
Since its debut, SRAM has expanded Eagle across multiple tiers: NX Eagle, GX Eagle, X01 Eagle, and XX1 Eagle, offering options for every type of rider and budget. Each level shares the same core 12-speed technology, allowing components to be interchangeable across Eagle drivetrains. This means a rider can mix and match cassettes, derailleurs, and chains between NX, GX, X01, and XX1 while maintaining smooth, reliable shifting.
Compatibility Across SRAM Eagle Products
One of the standout advantages of the SRAM Eagle ecosystem is its cross-tier compatibility. A GX Eagle cassette like the XG-1275 can be used with NX, X01, or XX1 Eagle derailleurs without issue. Chains and shifters are designed to work seamlessly across the 12-speed range, and the Eagle chainring and derailleur geometry ensures optimal chain retention and smooth engagement even under heavy loads.
This compatibility makes it easier for riders to upgrade parts gradually or replace components without having to overhaul their entire drivetrain. Whether you’re riding entry-level NX Eagle, mid-tier GX Eagle, or elite XX1 Eagle, the Eagle platform guarantees consistent performance, wide gear range, and durability.
