The relationship between bottom bracket spindle and bearing is the core of DUB™ technology. It's where stiffness meets durability. We 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.
