Quarq DZero & SRAM AXS.

Quarq’s next-generation power meter platform. New measurement circuit, revised strain gauge design, improved accuracy throughout the pedal stroke, and software advances.

Named after the D0 Experiment, one of science’s most accurate and innovative projects to detect subatomic particles moving at the speed of light. Quarq DZero represents 10 years of technical innovations and 150 technology iterations, to produce one of the most advanced power meters on the market.

Measure where it matters. The sole job of the crankset is to convert the effort from both legs to forward motion - this makes it the perfect place to directly measure power.

Understand, analyze and improve what wins you races — power output from your two legs. DZero is programmed with over 10,000 data points to ensure reading within 1.5% accuracy under all conditions.

Built to last. IPX7 waterproof rating, 2-year warranty, free firmware updates and worldwide support. Their location in the crank also makes them much less prone to damage than a pedal based power meter.

Simple to install and move between bikes. Compatible with every bottom bracket - including Boost 148 (52mm chainline) mountain bikes and BB386EVO bottom brackets.

Integrates with the free Qalvin app to set the zero offset, check battery voltage, run diagnostics and perform firmware updates. Dual Bluetooth low energy technology and ANT+ let you choose how to capture the data.

Power is the most consistent and quantifiable measure of training and race performance. This differs from measurements like heart rate - an aerobic response that is an indicator of effort and conditioning - or speed / cadence - a result influenced by many factors.

Harness your power.

  • Eliminate guesswork from training and race day.
  • Accurate baseline to measure improvements
  • Analyse your pedal stroke
  • Help to define your weaknesses.
  • Train specifically for the demands of your event.
  • Aerodynamic position testing.
