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.
This power meter works for every discipline: Road, triathlon, time trial, and cyclo-cross. The chainrings are replaceable should your bike, discipline, or ability change.
A direct force power meter that measures total power output from both legs with +/-1.5% accuracy
Dual Bluetooth low energy and ANT+ let you choose how to capture the data
Uses a hidden bolt to mount the chainrings – compatible SRAM chainrings ensure the derailment pin lines up behind the crank arm
10K – programmed with over 10,000 data points to eliminate temperature effects on power measurement
AxCad – A multi-axis accelerometer switches the power meter on and measures cadence, simplifying installation and operation
Breakthrough Materials – Exogram™ hollow carbon fiber crank arms – the lightest, strongest crank arms we make – minimize weight and maximize speed
Easy to use (and reuse) – LED indicator and visible ANT+ ID
The replaceable CR2032 battery never leaves you without power
Manual and automatic zeroing make it truly set and forget
Built to Last – IPX7 waterproof rating, 2-year warranty, free firmware updates, and acclaimed international support
Moves with you from bike to bike
With Quarq's free Qalvin BLE mobile app – available for iOS ® and Android – you can set the zero offset, check battery voltage, run diagnostics, and perform firmware updates.
