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. FEATURES: 6000 series forged aluminum arms DUB™ technology features a uniform approach to bottom bracket fitment, better sealing against contamination and is forward and backward compatible. ISO 4210 compliant. See Declaration of Conformity for details.
