Sram X01 Eagle 1x12S Boost DUB crankset

Strength is how the X01 Eagle™ DUB™ crankset takes capability to places never before reached. It’s the strongest crank in the entire Eagle™ ecosystem, and it holds this status at a weight that is hard to fathom. Featuring industry-proven and rider-beloved DUB™ technology to radically simplify the relationship of spindle to bottom bracket, delivering unprecedented simplicity, compatibility and durability. The X01 Eagle™ DUB™ Crankset also comes with Eagle™ Colorsystem, in the X01® master colorway - to go perfect with all other available cassette and chain colors – from Black to Gold to Rainbow, and now Copper. With a raw aluminum finish on the X-SYNC 2™ chainring teeth – to keep looking fresh throughout its long lifespan.

Technology

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.

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.

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.

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.

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.
