SRAM NX Eagle Boost DUB 170mm Direct Mount 32T Crankset Black

SRAM delivers EagleT styling and performance to the newest addition to the EagleT ecosystem. The NX crankset is designed for SRAM's X-SYNCT2 chainrings and is engineered for complete chain control - each tooth's profile is precisely engineered to work quietly, efficiently and securely with the EagleT chain's inner and outer links. DUBT 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 you can benefit from a new measure of performance and durability.

DUBT Technology
The relationship between bottom bracket spindle and bearing is the core of DUBT 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.
