QUARQ DZero Power Meter Spider for Specialized Crank - 110 BCD - Compact

QUARQ DZERO: TEN YEARS OF INNOVATION, PLUS NEW FEATURES

 
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.
