Power every ride with the Quarq DZero DUB. Designed for most 10 speed & 11 speed drivetrains, delivering on reliability & accuracy.
Reach new goals and explore new roads with a power meter that delivers on accuracy, durability, and reliability. The Quarq DZero DUB is built with broad compatibility and will work with most 10 speed and 11 speed chainrings. Build the power meter that best fits your bike; choose between 110 BCD or 130 BCD power meter spider, the crank length to fit you, and the compatible SRAM DUB bottom bracket for your bike.
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.
Quarq’s next-generation DZero power meter platform is named for the D0 Experiment, one of science’s most accurate and innovative projects to detect subatomic particles moving at the speed of light.
