SRAM GX Eagle Groupset 12-Speed 10-52 XD Drive 32T x 170mm "Boost" Dub Lunar

GX Eagle Groupset

Day in, day out, this is the Eagle ecosystem at its best. GX Eagle combines the full-featured capability of Eagle technologies, in a group that realizes the potential within every build. This is where you’ll find the best aluminum MTB crankset we make. GX Eagle has its own version of our new, 520-percent range, 10-52t cassette, for more top end speed or a more comfortable climb—should you choose to run it. If not, GX Eagle is backwards compatible, making replacement parts at the ready. Like other Eagle groups, it gets its own group master colorway as part of our new Eagle Colorsystem, allowing for full group or fully curated builds. It’s the simplest, most trouble-free drivetrain system ever made, offering the freedom to mix and match with any component within the expanded Eagle ecosystem.

Technology

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 2x11 drivetrains.

DUB

The relationship between bottom bracket spindle and bearing is the core of the DUB technology. It's where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler - better integrating the relationship between chainring, crank, spindle, and bottom bracket. It's this approach to developing a complete system that equals better drivetrain performance.

GX Eagle Rear Derailleur

Riders want the derailleur to do its job shifting on command, whether under climbing load or the stage finish. The GX Eagle derailleur gets it done with an updated cage architecture that improves chain management. Refined to work with the new 10-52t cassettes, it’s also backwards compatible for the 10-50t versions. Giving riders choice, because that’s how it should be. Finished with the new GX Eagle signature colorway – to compliment any cassette and chain colorway a rider wants from the Eagle Colorsystem. Further proof that the GX Eagle derailleur is there for one thing - to do the job.

• Backwards compatible, works with both 10-50t and new 10-52t cassettes.
• Updated cage architecture provides better chain retention and precise shifts.
• Comes in GX Eagle signature colorway as part of Eagle Colorsystem and goes with all colors of Eagle cassettes & chains – from Black to Gold to Rainbow, to HardChrome and new Copper.
