QUARQ DZERO: TEN YEARS OF INNOVATION, PLUS NEW FEATURES
ONLY FOR USE ON QUARQ PRIME / SRAM POWER READY CRANKS.
Meet DZero, the next-generation platform in power meters — packed with 10 years of technical innovations, plus new features such as dual Bluetooth® low energy and ANT+™, a simplified product line and revised circuitry. Yet DZero power meters still maintain Quarq’s no-compromise principles — metrics that matter, solving real problems, ease of use and improving your performance.
When Quarq set out to build the next generation Quarq power meter, they wanted to build the best-performing power meter for every facet of cycling and triathlon, and for riders at every level.
Like its Quarq brethren, the new DZero measures power in the heart of the bicycle — the crankset spider, scientifically proven to be the place for the most accurate measurement. 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.
Works with traditional 5-bolt chainrings from most manufacturers. Variations include Hidden Bolt (HB) and Non-hidden Bolt (NHB). The DZero Power Meter Spider pairs with Quarq Prime. Existing owners can upgrade to a DZero spider if the power meter uses the 8-bolt interface. Free firmware upgrades with the Qalvin app.
10K temperature compensation
Eliminates variables caused by heat and cold to provide an unwavering record of your performance through all conditions.
Built to last

WHY THE DZERO NAME?
The team at Quarq are decidedly science geeks. The Spearfish, S.D., company was named after the quark, the elementary particle that has never been observed or isolated. The DZero detector involves an intense search for subatomic clues that could reveal the building blocks of the universe. It’s one of the world’s most sensitive and accurate devices — just like Quarq Power Meters.
