Sram XX1 Eagle 1x12S 34T Standard DUB SL crankset

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 has re-examined and re-engineered their crankset design. The all-new XX1 Eagle™ Carbon Tuned™ crankset is the lightest, stiffest and strongest to date. Sram DUB™ technology enhances this by simplifying the relationship of the spindle to the bottom bracket, and redefining the measure of durability.

Technologies

DUB
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 — and better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this clear system approach that equals better drivetrain performance.

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.

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

Eagle™
Eagle™ technology represents the 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.
