SRAM GX Eagle DUB Boost Crankset With X-Sync 2 Chainring

The new MY21 Eagle Ecosystem with 10-52, 520% range cassettes and all new exciting colourways

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.

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 520%, which is equal to 2×11 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.
