Technology

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 verything 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.
