DUBT TechnologyThe 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.
