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 with the accuracy within 1.5%, measuring both legs.
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.
