DUB
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-better integrating the relationship between chainring, crank, spindle, and bottom bracket. It's this approach to developing a complete system that equals better drivetrain performance.
