QUARQ DZERO: NEXT-GEN POWER METER FOR SRAM’S VENERABLE GROUPSET
Built for SRAM’s popular RED groupset, and compatible with all of SRAM’s road groupsets, the SRAM RED DZero Power Meter embodies 10 years of Quarq’s technology advances and adds new features such as dual Bluetooth low energy and ANT+ wireless data transfer, the new Qalvin BLE app and compatibility with BB386EVO bottom brackets.
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.
10K temperature compensation
Eliminates variables caused by heat and cold to provide an unwavering record of your performance through all conditions.
Built to last
An IPX7 waterproof rating, an easy-to replace CR2032 battery, a 2-year warranty, free firmware updates and acclaimed worldwide support.
Easy to use (and reuse)
Manual and automatic zeroing make Quarq power meters truly set and forget. The chainrings are replaceable should your bike, discipline or ability change.

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. BB30 versions ship with the spacers and wave washer required for BB386EVO installation.
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.
