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.

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.

New Features

  • Dual Bluetooth low energy technology and ANT+ let you choose how to capture the data.
  • A simplified product line makes 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.

Technology

DZero is packed with 10 years of technical innovations and 150 documented technology iterations.

The Heart Of Your Bicycle

The sole job of the crankset is to convert the effort from both legs to forward motion. It is the perfect place to measure power.

Designed To Make You Faster

Quarq’s direct force power meters measure what wins races — total power output from both legs — with 1.5% accuracy.

Built To Last

All power meters have an IPX7 waterproof rating. They feature a 2-year warranty, free firmware updates and acclaimed worldwide support.

For Past, Present & Future

The DZero road power meters work for every discipline. The chainrings are replaceable should your bike, discipline or ability change.

10K Temperature Compensation

Each power meter is programmed with over 10,000 data points to eliminate temperature effects on power measurement.

A Companion Digital Wrench

With Quarq’s free Qalvin app you can set the zero offset, check battery voltage, run diagnostics and perform firmware updates. For free.
