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 BLE App, DZero represents the state of the art in power meter technology.

Power Meter Features

 

ANT+™ and BLE

The ANT+ wireless and Bluetooth® low energy give you the flexibility to choose any ANT+ or BLE compatible head unit.

 

10K™ Active Temperature Compensation

Each power meter is individually programmed using more than 10,000 data points to eliminate temperature effects on power measurement. Temperature compensation is computed and applied every pedal stroke.

 

AxCad™ Accelerometer Cadence

AxCad offers an alternative to magnet-based measurement - for convenience and for bikes where it's difficult to install a magnet.

 

Power Balance™

Power Balance uses crankset torque to display the ratio of power generated in the right drive stroke (12 o'clock to 6 o'clock) versus the left drive stroke (6 o'clock to 12 o'clock) for each crank revolution. Power Balance is used to test asymmetry and is an useful aid for injury recovery.

 

Omnical™

OmniCal means power measurement is independent from chainring selection. You can swap chainrings without impacting accuracy.

 

Exogram™ and CARBON TUNED™

Exogram hollow carbon crank arms and Carbon Tuned crank arms are the lightest and strongest crank arms we make for Road and MTB respectively. They maximize the stiffness to weight ratio.

 

Tool-free, user-replaceable battery

Quarq power meters use an industry standard CR2032 battery with over 200 hours of riding time.

 

LED

The flashing green and red LED aids installation, pairing with a head unit, zeroing and troubleshooting.

 

+/- 1.5% accuracy

Each power meter is individually calibrated at the factory and calibration values are stored in the power meter for seamless operation.

 

2-Year Warranty

All power meters feature a 2-year warranty.
