Stronger, stiffer, and lighter than ever; that is exactly what you can expect with the Quarq DUB crank arm assembly. Paired with the DZero or DFour DUB power meter spider and the DUB bottom bracket, the Quarq DUB crank arms assembly builds a power meter that can handle the toughest of conditions.
Our Hollow Carbon Construction starts in the crank arm and extends into the crank's spider, maximizing the stiffness to weight ratio.
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.
