SRAM NX Eagle Fat Bike 4" DUB Crank DM X-SYNC 30 teeth 12x black

The SRAM NX crankset delivers Eagle styling and performance to the newest addition to the Eagle ecosystem. Designed for SRAM's X-SYNC2 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.

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.
