  • SRAM NX Eagle 12 Speed Mountain Bike Groupset

    The NX Eagle 12 Speed Mountain Bike Groupset from SRAM offers all the top technologies of SRAM's XX1 and X01 drivetrains at a price that won't break the bike. This groupset includes SRAM's well-known bottom bracket 'DUB' system, which improves performance between the crank, spindle and bottom bracket for a smoother ride whatever the terrain. 



    The NX Eagle DUB chainset is engineered to deliver Eagle 12 speed performance and styling that everyone can enjoy. In addition to the excellent chain retention that’s provided by the X-SYNC™2 chainrings, this chainset provides outstanding power transfer and durability due to the highly advanced DUB bottom bracket system.

    Chainset Features: 

    • Material: Aluminium (chainring), 7000 series Aluminium (crank arm) 
    • Bottom Bracket Interface: SRAM DUB 
    • Chainline: 49mm 
    • Bolts: Direct mount 
    • Recommended Chain: SRAM Eagle 
    • Compatibility: All Eagle drivetrains 
    • Weight: 705g (175mm, 32T ring)


    Despite the NX model falling under the “entry-level” category, SRAM has still managed to pack in some of its best technologies. These include ZeroLoss™ and X-Actuation™ technologies, which combine to offer instant shifts and sharp shifting across the full cassette range.

    Shifter Features: 

    • Material: aluminium/Plastic, Stainless Steel hardware 
    • Compatibility: All Eagle drivetrains 
    • Matchmaker compatible for dropper remote and brake lever integration 
    • Weight: 112g

    Rear Derailleur:

    As seen on the top-of-the-line XX1 and X01 models, the NX Eagle rear derailleur also adopts SRAM’s 1x specific X-Horizon™ cage design. This carefully engineered mechanism ensures capacity for the huge 11-50T cassette and compliments the smooth Performance of an Eagle 12 speed system. This derailleur also boasts SRAM’s Type-3 Roller Bearing Clutch™ for unrivalled durability and quiet consistent performance.

    Rear Derailleur Features:

    • Material: Aluminium (cage), Steel (spring, pulley), Stainless Steel (hardware) 
    • Max Tooth: 50T 
    • Compatibility: All Eagle drivetrains 
    • Weight: 339g


    At the core of all Eagle drivetrains, the 12 speed Eagle chain is designed and manufactured with SRAM’s Eagle™ architecture. This ensures perfect compatibility with all of the other components in any Eagle ecosystem for highly efficient, smooth and quiet shifting that you can take for granted each and every time you hit the trails.

    Chain Features: 

    • Material: Steel 
    • Rivet Type: Solid pin 
    • Compatibility: All Eagle drivetrains 
    • Weight: 278g (126 links)


    SRAM designed its NX Eagle cassette to provide riders with the option of upgrading to 12 speed, but without the need for a hub or wheel upgrade. Ready to fit straight on to standard “splined-drive” freehubs and offering a massive  11-50T range, this cassette gives you the climbing range you need to attack the climbs and the smooth performance to get the most out of your other Eagle components. This cassette is also designed to be durable enough for the extra demands and abuse of E-MTB use.

    Cassette Features: 

    • Material: 8 lightweight, stamped steel cogs and 4 high-strength steel cogs pinned onto an aluminium spider 
    • Recommended Chain: Eagle chain only 
    • Compatibility: All Eagle drivetrains 
    • Weight: 615g


    • X-Sync 2: X-Sync 2 Eagle is the next evolution of SRAM X-Sync technology. The aggressive tooth 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. 
    • DUB™ Technology: The relationship between bottom bracket spindle and bearing is the core of DUB™ technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler, by better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this clear system approach that equals better drivetrain performance.   
    • Zero Loss: The gear cable is engaged instantly with zero loss of movement when you press a shift trigger, every gear change is instant and precise. 
    • Matchmaker X Integrated: You can put everything from your XLoc suspension lockout, your SRAM shifters and brake levers as well as your Reverb XLoc remote, all on two clamps. It's the ideal way to put everything within easy reach and tidies up your bike's cockpit. 
    • 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: The Roller Bearing Clutch delivers maximum drivetrain stability even through the most punishing terrain. This stability benefits the drivetrain dramatically, as derailleur bounce and chain slap are eliminated without sacrificing precision. 
    • X-Actuation: Developed specifically for SRAM 1x drivetrains, X-Actuation keeps shifting sharp and consistent across the entire cassette. This makes gears easy to index and provides exceptional performance. 
    • X-Horizon: The X-Horizon ‘straight parallelogram' design limits all movement on the horizontal axis, which makes ghost shifting impossible while also reducing shift force. The large upper pulley offset design maintains a constant chain gap across all gears and guarantees faster and more exact shifting. 
    • Flow Link: 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 and a flatter outer-plate that can withstand greater shifting angles. This means more consistent chain riveting and enhanced overall strength is achieved. 
    • PowerLock: SRAM chain engineers developed PowerLock as a tool-free and consistent way to connect mountain bike chains. While PowerLock does not require special tools for installation, the especially tight tolerances of 10, 11 and 12-Speed drivetrains mandate that each PowerLock is good for a one-time application only. 
    • X-Glide 2: This optimised cassette technology, which has been custom designed for the Eagle drivetrain is the next generation of X-Glide shifting. It provides quick, precise, power-on shifting performance throughout the gear range, and increases chain retention on larger cogs.
