SRAM SX Eagle – Affordable Performance at BIKE24
The SRAM SX Eagle is your budget-friendly entry point into SRAM’s modern 1x12-speed drivetrain world. As part of the well-thought-out Eagle ecosystem, it makes many innovations from higher-end groups like NX and GX Eagle more affordable. It’s a smart choice for your first mountain bike build or an upgrade from 9- or 10-speed drivetrains.
Thanks to its outstanding price-performance ratio, SRAM SX Eagle broadens the gear range of many beginner-friendly complete bikes. From forest paths and gravel tracks to moderate trails or e-MTB tours – this drivetrain delivers reliable shifting and the gear range you need for steep climbs and fast descents. It’s the perfect starting point for a bike you can upgrade step by step – fully compatible with all Eagle components.

The SX Eagle Series at a Glance
The SRAM SX Eagle line includes everything you need for a complete 1x12-speed drivetrain. It’s ideal if you want a forgiving, upgradeable setup for after-work rides, weekend tours or your first e-MTB adventures. At its core is the robust SX derailleur, paired with a wide-range PG cassette (11–50 teeth), a crisp-shifting trigger shifter and a solid crankset with Direct-Mount chainring. Choose between 49 mm standard and 52 mm Boost chainlines. Disc brakes aren’t included, but the SX Eagle pairs perfectly with SRAM Motive or DB8 brakes.
SRAM SX Eagle Derailleur
The SRAM SX derailleur brings the key Eagle technologies to the entry level. Its X-HORIZON design prevents unwanted shifting (ghost shifting), while the Roller Bearing Clutch damping minimizes chain slap on rough trails. With the practical Cage Lock mechanism, you can remove or install your rear wheel in no time.
SRAM SX Eagle Cassette & Crankset
The HG-compatible PG cassette offers an 11–50 T range with a 454% gear spread, giving you the right ratio for steep climbs and fast descents. Because it fits the common HG freehub standard, it’s the ideal choice for cost-effective upgrades on entry-level or older trail bikes. The sturdy aluminum crankset comes with a durable steel Direct-Mount chainring featuring SRAM’s X-SYNC 2 tooth profile for secure chain retention.
SRAM SX Eagle Shifter
The SX Eagle shifter ensures crisp, instant gear changes thanks to X-ACTUATION and Zero Loss technology. For e-MTBs, there’s also a Single Click version that shifts one gear per press to protect the drivetrain under motor load and prevent mis-shifts.
Innovation for Everyone – Top Tech at a Great Price
The SRAM SX Eagle may be the entry-level groupset, but it shares the same technological DNA as its higher-end siblings. Core innovations such as the X-HORIZON derailleur design and the X-SYNC 2 chainring profile are standard here as well. Its greatest strength, however, lies in its full integration into the Eagle ecosystem, giving you complete compatibility and a future-proof upgrade path.
- Cage Damping & Cage Lock: The cage damping system keeps the chain tight even on rough terrain. With Cage Lock, you can lock the SRAM SX derailleur cage for quick and easy wheel changes.
- Eagle Gear Range: With 12 sprockets (11–50 teeth) and a 454% gear range, your SRAM SX Eagle groupset is ready for anything – from steep climbs to fast descents.
- X-SYNC 2: The advanced narrow-wide tooth profile of the chainring meshes perfectly with the chain, keeping it securely in place even without a chain guide.
- Eagle Ecosystem: All components are fully cross-compatible for seamless upgrades.

Important Questions and Answers About SRAM SX Eagle
- Is SRAM SX Eagle compatible with my old wheelset?
Yes, in most cases. The SX Eagle cassette fits standard HG freehubs, making it ideal for upgrading older mountain bikes to a modern 1x12 setup without replacing the wheel or freehub body. - What’s the main difference between SRAM SX and NX Eagle?
The main difference lies in weight and materials. The SX Eagle uses more steel components (such as the chainring and cassette), making it slightly heavier and a bit less durable in long-term use due to some plastic parts. The NX Eagle, on the other hand, features more machined aluminum components, which reduces weight and improves durability. - Is SRAM SX compatible with my frame?
The crankset is designed for Truvativ PowerSpline bottom brackets, which are compatible with standard BSA shells.
