SRAM GX Eagle DUB Shifting Groupset Boost 170mm lunar

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.

GX Eagle Trigger Shifter
Of all the components that make up a mountain bike drivetrain, the shifter doesn’t exactly get a lot of spotlight time. But as the rider’s literal command and control center, the GX Eagle shifter is more than worthy of recognition. With intuitive thumb actuated triggers, the positive feel gives the right rider input to make shifts crisp and discernible every time. What’s more, its already legendary reliability continues for all-day epics, and all-time experiences. Plus, it features an aluminum trigger that’s ready for inevitable punishment, and MatchMaker X compatibility. Precise and durable, it’s the hard-working, no-compromise shifter keeping riders in the right gear, every ride.

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 master 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.

GX Eagle DUB Crankset
Some riders test their limits more than others. For these riders, the GX Eagle DUB crankset allows them to go all in, every day they ride. The best aluminum crankset we make, engineered to deliver consistent performance every ride. Featuring our X-SYNC 2 tooth profile chainring for complete chain control. Each tooth's thickness is toleranced and controlled to work seamlessly with the chain's inner and outer links. DUB technology’s patented spindle design and bottom bracket provides a uniform approach to fitment, better sealing and forward and backward compatibility. Simply put, the forged aluminum GX Eagle DUB crankset is the no frills choice of riders who know.

XG-1275 Eagle Cassette
The new 10-52 Eagle cassette for riders who prioritize all day function over anything else. With an expanded, 520-percent gear range giving riders more ability to spin and recover on the burliest climbs. Featuring FULL PIN technology that uses lightweight, precision engineered steel cogs permanently connected with high-strength stainless steel pins. An open design similar to our X-DOME cassette that aids in mud clearance, giving riders crisp shifting performance and longer component life.

GX Eagle Chain
The GX Eagle chain is designed with SRAM’s Eagle geometry, the GX Eagle chain features solid pin construction, Eagle PowerLock and smooth, efficient shifting that you can count on every time out.
