Product Info

Cue that high pitched bird that's at the start of all those nature scenes: 12 speeds! SRAM's Eagle technology has finally made it to their NX level, meaning you don't have to be a dentist to own the current state of the art. Shifter, crankset, cassette, chain, and rear D: all designed together to work as a complete system. Just grab a DUB bottom bracket and your bike is ready for all-mountain domination. From XC to enduro racing, Eagle has proven itself a simple and reliable drivetrain for all riders, letting you shift quickly through a wide range of gears. With a 32t chainring and 11-50t out back, your bike is ready for any terrain. The SRAM NX Eagle DUB Boost Groupset is for bikes with Boost spacing.

Product Details


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™ rear derailleurs deliver maximum drivetrain stability—even through the most punishing terrain. With Roller Bearing Clutch™ technology, derailleur bounce and chain slap are eliminated without sacrificing precision.


DUB™ TechnologyCompatible with all existing BB sizes and frames.

Forged Aluminum6000 Series aluminum, strong and light enough for any ride.

X-SYNC™ 2 Chainring32 tooth steel narrow wide chainring for max chain retention and durability.

28.99mm Axle DiameterStiffer than GXP yet lighter than BB30.


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

ZeroLoss™ZeroLoss simply means, well, zero loss—when you push on the lever, for an upshift or down shift, the cable is engaged instantly—zero loss of movement. There is no middle-ground where you're waiting for the shift to come. Gear changes are instant and precise.

MatchMaker X IntegratedThe MatchMaker X clamp is more than just a clamp. It’s like having Martha Stewart tidy up your cockpit. Since each clamp accepts up to three controls, you can put everything from your XLoc suspension lockout, your SRAM shifters and AVID brake levers as well as your Reverb XLoc remote, all on two clamps. Short of genetically engineering longer thumbs, it’s the ideal way to put everything within easy reach. Just like Martha would.


PowerGlide IICassette technology optimized for offroad. More reliable. More durable. Better performing, thanks to an optimal tooth profile and shift ramp design for quick and positive index shifting. Go climb a mountain.

11-50 Tooth Gear RangeA perfect fit for any ride with optimized gear steps across entire range.

Steel and Aluminum8 lightweight, stamped steel cogs and 4 high-strength steel cogs pinned onto an aluminum spider.


Flow LinkUltra-smooth chain inner-plates are completely devoid of square edges, resulting in a chain that engages the cassette and chainring with far less friction, for quieter performance and better wear life. The design allows a narrower overall profile that can withstand greater angles, and also allows for a flatter outer-plate, which means more consistent chain riveting and enhanced overall strength.

X-Sync™ 2The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC EAGLE™ design reduces friction and the accumulation of mud, grit and grime.

PowerLock® Quick LinkSRAM chain engineers developed PowerLock® as a tool free, sure, and consistent way to connect chains.
