Affordable Performance
The GX Eagle 12sp DUB Boost Groupset offers you the same gearing range and technologies as seen on SRAM’s XX1 and X01 Eagle DUB models, but at a price that puts it within the reach of the masses! It’s designed to help you realize your bike's true potential and has been designed, tested and proven to deliver lightweight, durable and reliable performance on all trail types. Plus, SRAM's revised and updated “DUB” bottom bracket system provides improved integration between the crank, spindle and bottom bracket.

DUB and Boost
The chainset adopts SRAM’s revised and updated “DUB” bottom bracket system, which provides improved integration between the crank, spindle and bottom bracket. This particular groupset is also specifically designed for “Boost” Type frames so the chainset has a wider chainline, ensuring clearance with these frame's wider rear ends.

Efficient Cranks
The SRAM GX Eagle DUB Boost Crankset is designed for tackling any terrain you may encounter when riding a mountain bike. It has been fine tuned to deliver consistent performance every time you are out on the bike. GX Eagle DUB also provides outstanding power transfer and durability due to the highly advanced DUB bottom bracket system. Plus with X-Sync 2 chainring with its carefully engineered tooth profile, you’ll enjoy exceptional chain control and pedalling performance.

Zero Loss Shifting
The SRAM GX Eagle trigger shifter is the control centre of the GX Eagle drivetrain. Every gear, up or down the cassette can be reached via the movement of your right thumb. As the Eagle 12-speed drivetrain uses X-Actuation and Zero Loss, shifting in any scenario is smooth, crisp, and effortless.

Rear Shifting that Works
The SRAM GX Eagle 12-Speed Rear Derailleur has a smooth shifting curve and provides precise, consistent and quiet drivetrain performance, thanks to trickle down technology from higher end Eagle drivetrain models. X-Actuation and X-Horizon technologies ensure ghost shifting and random jumps between the cassette cogs are a thing of the past.

50 Teeth
Concur even the steepest terrain with the Eagle Cassette providing you with the correct gear ratio no matter what your riding situation may be. Should you find yourself climbing the steepest technical mountain single-track or racing down through flowing forest trails, you can be sure that this cassette will meet your performance requirements.

Getting Technical
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.

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.

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.

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-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.
