SRAM GX Eagle crankset DUB 12-speed Directmount FAT

GX Eagle DUB Crankset

Some riders test their limits more than others. For these riders, the GX Eagle DUB crankset allows them to go all in, every day they ride. The best aluminum crankset we make, engineered to deliver consistent performance every ride. Featuring our X-SYNC 2 tooth profile chainring for complete chain control. Each tooth's thickness is toleranced and controlled to work seamlessly with the chain's inner and outer links. DUB technology’s patented spindle design and bottom bracket provides a uniform approach to fitment, better sealing and forward and backward compatibility. Simply put, the forged aluminum GX Eagle DUB crankset is the no frills choice of riders who know.

• Our best aluminum crankset.
• Direct mount interface compatible with chainrings across the entire Eagle Ecosystem.
• Master GX colorway as part of Eagle Colorsystem – pairs with all cassettes and chains, from Black to Gold to Rainbow to HardChrome and all-new Copper.

Technology

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

Eagle
Eagle technology represents our newest 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 500%, which is equal to 2x11 drivetrains.

X-SYNC 2
SRAM X-SYNC 2 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-SYNC 2 Eagle design reduces friction and the accumulation of mud, grit and grime.

DUB
The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.
