Sram NX Eagle 1x12S Boost DUB crankset

The Sram NX crankset delivers Eagle™ styling and performance to the newest addition to the Eagle™ ecosystem. Designed for Sram’s X-Sync™2 chainrings, the NX crankset is engineered for complete chain control—each tooth’s profile is precisely engineered to work quietly, efficiently and securely with the Eagle™ chain’s inner and outer links. DUB™ technology features a better-engineered bottom bracket and a new spindle design, which together allows for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of performance and durability.

Technology

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.

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.

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.
