The DZero DUB power meter spider by QUARQ - packed with technology


The QUARQ DZero DUB power meter spider is equipped with power measurement sensors and serves as an upgrade for DUB cranks with an 8-bolt interface, e.g. the DUB Carbon crank. It can be used for traditional 5-arm chainrings and 10 or 11-speed drivetrains. The power meter platform contains more than a decade of experience with power measurement technology. DFour impresses with excellent temperature compensation, 200 hours battery life, ANT+ and Bluetooth data transfer and last but not least with MagicZero™, an automatic calibration while riding. Add the smart DUB bottom bracket technology and you get a product that is second to none in stiffness, reliability and weight optimisation.

QUARQ Operating Principle
The crankset forms the heart of your bike. Their only task is to convert the force of both legs into forward motion - the perfect place to measure performance.
Power meters calculate power by measuring torque (pedal force) and angular velocity (cadence). Power = torque x cadence. When you pedal, all parts of the bicycle drivetrain shift (bend) slightly under the load. Power meters are designed using FE analysis so that these displacements take place in a very controlled manner and at specific locations in relation to the applied load. Strain gauges are used to measure this displacement and calculate the applied torque. Reed switches are used to calculate the cadence.

DZero
DZero is QUARQ's next generation power meter, named after the DZero Experiment, one of the most accurate and innovative scientific projects to discover subatomic particles. With a revised measurement loop, optimised strain gauge design, increased accuracy and the features of the Qualvin and SRAM AXS app, DZero represents the state of the art in power meter technology. You can choose between Bluetooth LE and ANT+ technology for data transfer. A simplified product line makes it easier for you to find the right power meter for your bike.

OmniCal™
The power measurement depends on the choice of the right chainring. Change from a Road to a Time Trial chainring without sacrificing accuracy. No recalibration necessary.

MagicZero™
Calibration takes place automatically during the ride. You don't need to pedal backwards or perform a manual calibration from your computer.
