The SRAM NX Eagle DUB Boost Groupset is the ideal gateway into the legendary Eagle 1x12 drivetrain ecosystem, delivering dependable performance, wide gear range, and smooth shifting for trail and all-mountain riders. Built with proven SRAM technologies and designed for Boost™ spacing, this groupset gives you the freedom to customize your bike while enjoying the simplicity and reliability of a single-chainring setup.
The NX Eagle drivetrain shares key design DNA with SRAM’s premium XX1, X01, and GX Eagle groupsets, making it fully compatible across the Eagle lineup. This means easy upgrades, seamless integration, and confidence that every component works together flawlessly.
With 12 speeds and an 11–50T wide-range cassette, the NX Eagle Boost groupset delivers exceptional climbing ability and efficient cadence control, ensuring you always have the right gear for any terrain.
SRAM’s DUB™ technology simplifies bottom bracket compatibility by using a single oversized spindle across multiple standards. This results in improved crankarm stiffness, long-term durability, and easier installation—while maintaining lightweight performance.
The NX Eagle crankset is designed specifically for X-SYNC™ 2 chainrings, offering complete chain control and reduced chain drop, even on rough trails.
Each tooth on the 32-tooth X-SYNC 2 chainring is precisely engineered to engage perfectly with the Eagle chain’s inner and outer links. This design provides:
Quieter operation
Improved pedaling efficiency
Superior chain retention in all conditions
Whether climbing technical singletrack or descending at speed, the drivetrain remains stable and responsive.
The NX Eagle derailleur features SRAM’s proven X-HORIZON™ 1x-specific design, which minimizes unwanted movement and improves shifting accuracy. A 14-tooth X-SYNC lower pulley supports the cassette’s wide 11–50T range, contributing to a smoother pedaling feel.
The Type-3 Roller Bearing Clutch reduces chain slap, enhances durability, and keeps drivetrain noise to a minimum—perfect for aggressive trail riding.
The NX Eagle chain is built using genuine SRAM Eagle architecture, ensuring full compatibility with all Eagle components. Featuring solid pin construction and the reliable Eagle PowerLock, it delivers smooth, consistent shifting and long-lasting performance ride after ride.
