Eagle Technology revolutionized the mountain bike experience by offering riders a 1x drivetrain solution that is purpose-built to be lightweight, strong and intuitive, with the gear range to ride on any terrain. NX Eagle drivetrain is the newest addition to the Eagle 1x ecosystem, and shares technologies with XX1, X01 and GX drivetrains, which makes it 100-percent compatible within the Eagle ecosystem. NX Eagle delivers an ease of entry that will bring the benefit of Eagle performance to more riders than ever before.

The SRAM NX crankset delivers Eagle styling and performance to the newest addition to the Eagle ecosystem. Designed for SRAM’s X-SYNC2 chainrings, the NX crankset is engineered for complete chain control—each tooth’s profile is precisely engineered to work quietly, efficiently and securely with the Eagle chain’s inner and outer links. DUB technology features a better-engineered bottom bracket and a new spindle design, which together allows for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of performance and durability.


  • WEIGHT: 705g (175mm, 32T ring)
  • COMPATIBILITY: All levels of Eagle™ 12-speed drivetrain systems, All major bottom bracket standards.
  • HARDWARE: Direct mount
  • OPTIONS: 165mm, 170mm, 175mm
  • MSRP PRICE: $105-121 | €116-135* | £104-120* (*Includes VAT)


X-SYNC2 Eagle™ is the next evolution of SRAM X-SYNC technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC2 Eagle™ design reduces friction and the accumulation of mud, grit and grime.

BOOST is a new wheel and drivetrain specification that opens the opportunity for improved frame geometry with shorter chain stays, wider and stiffer suspension pivots, a wider range of chainring options as well as more clearance for bigger tires and wider, stiffer wheels.


This new NX Eagle derailleur features the proven SRAM 1x-specific X-HORIZON design. The larger, 14-tooth X-SYNC lower pulley easily facilitates 11- to 50- and 10- to 50-tooth cassette capacity, and also adds to NX Eagle’s overall smooth-pedaling feel. The Type-3 ROLLER BEARING CLUTCH provides quiet, consistent performance and durability.


  • WEIGHT: 339g
  • COMPATIBILITY: All levels of Eagle™ 12-speed drivetrain systems
  • MATERIALS: Aluminium/Steel
  • HARDWARE: Stainless steel
  • OPTIONS: Black
  • MSRP PRICE $107 | €119* | £105*  (*Includes VAT)


The X-HORIZON 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 gap across all gears.

With CAGE LOCK technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.

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

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.


New NX Eagle trigger shifter means on-demand gear selection throughout the entire wide range Eagle cassette. The massive range means you never have to worry about having the right gear for the terrain. NX Eagle means easy, intuitive shifting every time for every rider.

  • Also available as a E-MTB specific Eagle™ shifter option limiting the pull lever to a single engagement.


  • WEIGHT: 112g
  • COMPATIBILITY:All levels of Eagle™ 12-speed drivetrain systems
  • MATERIALS: Aluminum/Plastic
  • HARDWARE:Stainless steel bolts, MatchMaker™ X
  • OPTIONS: Black
  • MSRP PRICE $42 | €38* | £34* (*Includes VAT)


ZERO LOSS 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.

X-ACTUATION™ developed specifically for SRAM 1x keeps shifting sharp and consistent across the entire cassette.


Ride anywhere with the wide-range PG-1230, 11- to 50-tooth Eagle cassette. The NX cassette gives riders every bit of the climbing range that the Eagle ecosystem affords with a simple upgrade to splined-drive body wheels. The PG-1230 is the only Eagle cassette designed to be durable enough to withstand the increased demands of E-MTB applications and a perfect solution to heavy-duty use and abuse.


  • WEIGHT: 615g
  • COMPATIBILITY: All levels of Eagle™ 12-speed drivetrain systems

X-GLIDE™2 is next generation of SRAM X-GLIDE technology optimized for the Eagle™ 12-speed cassette. It provides quick, precise, power-on shifting performance throughout the gear range, and increases chain retention on larger cogs.


The basis of every Eagle drivetrain is its chain—and the NX Eagle chain is designed and manufactured using genuine SRAM’s Eagle architecture, so it is fully compatible with every other component in the Eagle ecosystem. The NX Eagle chain features solid pin construction, Eagle PowerLock® and smooth, efficient shifting that you can count on every time out.


  • WEIGHT: 278g
  • COMPATIBILITY: All levels of Eagle™ 12-speed drivetrain systems

  • OPTIONS: Grey
  • MSRP PRICE $26 | €29* | £26*  (*Includes VAT)


FLOWLINK™ Ultra-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.

Jenson USA’s Take: SRAM NX Eagle

SRAM NX Eagle is the natural progression of the Eagle 12-speed drivetrain movement.  While this new product line is not revolutionary or unexpected, it is highly desirable.  This ushers in a high performing, value-oriented group that gives riders even more options to create and build the bike that is right for their riding style and pocket book.  With it’s compatibility with the rest of the Eagle groups, this will allow riders to pick-and-choose the components that give them the most bang for their buck, while still prioritizing key components for weight, performance, and value.  Further, the use of a standard splined freehub for the 11-50t cassette means that riders who weren’t ready to jump onto the XD driver body system can migrate over to a 12-speed Eagle platform without having to modify or replace their wheels.  We haven’t yet ridden this group, but we suspect that riders who have spent a lot of time on the higher-end offerings from SRAM will likely be able to feel some performance differences, and will likely want to stay within those higher-end groups.  But, large proportion of riders will find the new NX Eagle and GX Eagle groups more than competent on the trail, and will leave some money in your wallet for other upgrades, or gas money to go one epic mountain bike trips.  Check out SRAM’s press release info below for all the specs and details of this latest Eagle group.

Recommended rider:

Riders on a tighter budget, those who are hard on components and have to replace them often, or those who pick-and-choose their bike builds to prioritize getting the most performance for the least cost.
