The Quarq DZero Platform

Quarq's next-generation power meter platform, DZero, is named for the DZero Experiment, one of science’s most accurate and innovative projects to detect subatomic particles moving at the speed of light. DZero combines 10 years of accumulated Quarq advances with new features and a simplified product line.


With a new measurement circuit, a revised strain gauge design, improved accuracy throughout the pedal stroke and software advances built into the Qalvin App, DZero represents the state of the art in power meter technology.

Other new features include:

  • Dual Bluetooth low energy technology and ANT+, letting you choose how to capture the data.
  • A simplified product line, making it easier to choose and install the right power meter for your bike.
  • Increased compatibility, including Boost 148 (52mm chainline) mountain bikes and BB386EVO bottom brackets.
  • Quarq Prime Power Ready Cranksets that can be upgraded with a Quarq DZero power meter spider.

Like its Quarq brethren, the new DZero platform measures power in the heart of the bicycle -- the crankset spider, scientifically proven to be the most accurate place to measure power.

DZero power meters inherit 10K temperature compensation, easy-to-replace batteries, OmniCal (change chainrings without affecting accuracy), AxCad (accelerometer cadence – no magnet), an IPX7 waterproof rating and a 2-year-warranty.

The DZero platform includes the following systems:

Quarq Prime Power Ready Cranksets

In 2017 you will see Quarq Prime Power Ready Cranksets on bikes from Canyon, Felt, Fuji, Trek and others. Based on SRAM Force and Rival, they more than hold their own as standard cranks. Paired with a DZero power meter spider, Quarq Prime is the building block for a race-winning bike and rider combination.

Quarq will continue to support Quarq Power Meter Spiders for Specialized and Cannondale cranksets.
