SRAM NX Eagle 12 Speed Rear Derailleur: Your Gateway to Precision and Reliability

Embrace the Next Evolution of 1x Drivetrains

The SRAM NX Eagle™ 12 Speed Rear Derailleur ushers in a new era of efficiency, precision, and durability for riders ready to embrace the full benefits of the 1x drivetrain system. Leveraging the advanced technology and design prowess of SRAM, the NX Eagle rear derailleur is a testament to performance-oriented engineering.

X-HORIZON™ Design for Unmatched Shifting

At the core of the NX Eagle™ derailleur is the X-HORIZON™ design, a feature developed specifically for SRAM 1x drivetrains. This design limits all movement to the horizontal axis, making shifting more direct and reducing shift force. Whether navigating technical singletracks or powering through open trails, the X-HORIZON™ ensures precise and reliable shifting across the entire 12-speed cassette.

Expanded Cassette Compatibility

The NX Eagle™ rear derailleur is designed to accommodate a wide range of gearing options, supporting both 11-50 and 10-50 tooth cassette capacities. The inclusion of a 14-tooth X-SYNC™ lower pulley not only enhances this compatibility but also contributes to the smooth pedaling feel that riders have come to expect from SRAM Eagle™ drivetrains.

Type-3 ROLLER BEARING CLUTCH™ for Stability

The incorporation of SRAM's Type-3 ROLLER BEARING CLUTCH™ technology in the NX Eagle™ derailleur provides riders with a quiet and consistent performance, regardless of the terrain. This clutch mechanism ensures optimal chain tension, minimizing chain slap and promoting a more stable and durable drivetrain, so you can focus on the ride ahead with confidence.

Durability Meets Performance

With its robust construction and attention to detail, the NX Eagle™ 12 Speed Rear Derailleur is built to withstand the rigors of mountain biking. From epic all-day adventures to intense competitive events, riders can rely on the NX Eagle™ for smooth shifting and lasting performance ride after ride.

Unlock the Full Potential of Your Ride

The SRAM NX Eagle™ 12 Speed Rear Derailleur represents a significant leap forward for riders seeking to maximize the performance of their 1x drivetrain without breaking the bank.

With its advanced technology, expanded compatibility, and unwavering reliability, the NX Eagle™ is ready to take your riding experience to new heights. Embrace the future of shifting with SRAM NX Eagle™.

Technology of SRAM NX Eagle 12 Speed Rear Derailleur

Cage Lock- With Cage Lock technology in the rear derailleur, wheel removal and installation-as well as chain installation-becomes faster and simpler. Just push the cage forward to create slack and lock it into place.

Roller Bearing Clutch- Roller Bearing Clutch technology eliminates derailleur bounce and chain slap without sacrificing precision.

X-Actuation- Developed specifically for SRAM 1x, X-Actuation keeps shifting sharp and consistent across the entire cassette.

X-Horizon- This rear derailleur's "straight parallelogram" design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gay across all gears.

X-Sync- SRAM X-Sync 1x chainrings provide the highest level of performance and durability. The SRAM X-Sync tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync rings are an integral part of the SRAM 1x drivetrain. Accept no imitation.

Eagle- Eagle technology represents our newest 1x drivetrain technology. Eagle is a lighter, simpler, more durable and easier to use drivetrain. Eagle features all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 520%, which is equal to 2*11 drivetrains.
