SRAM XX1 Eagle DUB Chainset

True competitors are always looking for a performance advantage - a relentless pursuit of equipment that is lighter, stiffer, stronger and more durable. To create the best drivetrain possible, SRAM re-examined and re-engineered SRAM's crankset design. SRAM's all-new XX1 Eagle Carbon Tuned crankset is SRAM's lightest, stiffest and strongest to date. DUB technology enhances this by simplifying the relationship of the spindle to the bottom bracket, and redefining the measure of durability. DUB-powered cranksets deliver simplicity, compatibility and durability.

Technology

Carbon Tuned

Strength and stiffness where you need it, lightweight like you want it. Proprietary SRAM carbon lay-up design increases thickness and stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength.

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 x 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.
