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 onventional 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.
