SRAM NX Eagle DUB BOOST 12 Speed Groupset
SRAM NX Eagle DUB BOOST 12sp Groupset
The NX Eagle DUB 12 Speed Boost Groupset offers the same features, technologies and gear range as seen on SRAM'S top-end XX1 and X01 Eagle drivetrains.
However, the difference with NX Eagle is that it falls within the reach of more rider's budgets. It also adopts SRAM's revised and updated bottom bracket system called "DUB", which provides improved integration between the crank, spindle and bottom bracket. This particular groupset is specifically designed for "Boost" Type frames so the chainset has a wider chainline, ensuring clearance with these frame's wider rear ends.
Features: Chainset: The NX Eagle DUB Boost 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 (TM) 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: 52mm Bolts: Direct mount Recommended Chain: SRAM Eagle Compatibility: All Eagle drivetrains Shifter: 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 (TM) and X-Actuation (TM) 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 (TM) 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 (TM) 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 Chain At the core of all Eagle drivetrains, the 12 speed Eagle chain is designed and manufactured with SRAM's Eagle (TM) 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) Cassette 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 Technologies: 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 (TM) Technology: The relationship between bottom bracket spindle and bearing is the core of DUB (TM) 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... more details.

Groupsets is the name given to a complete gear and braking system, ready to be fitted to your new bike. By buying the whole lot in one convenient purchase you can both save money, as well as ensure that each component will be compatible with the rest. The main players in cycling groupsets are Shimano, SRAM and Campagnolo.

SRAM began life in Chicago in 1987, named after it's founders Scott, Ray And Sam, and is known primarily as a manufacturer of drivetrain and braking components. It's first revolutionary product was the twist action GripShift, which became available in 1988, with the MTB version released in 1991. In 1995, they launched their first ESP rear derailleur, which featured a 1 to 1 cable actuation ratio. The X.O drivetrain products were released in 2001, marking the introduction of the trigger shifter, and a year later, MTB Suspension pioneers RockShox was acquired. A year later Avid - a MTB Disc Brake company - was also acquired, giving SRAM more market share of the MTB industry. By 2006, a focus was shifted to producing road components in addition to their MTB stable, with the launch of Force and Rival groupsets. The following year, Doubletap was introduced, enabling users to switch gear in either direct using a single shifter. This steady growth was sustained, and over the years SRAM acquired several more cycling household brands, such as Truvativ (Chainsets and components), Quarq (power meters), Sachs (drivetrain components) and Zipp (carbon fibre goodies!).
