Description of Quarq AXS DZero DUB Power Meter Spider - Non-Hidden Bolt - 130 BCD - Standard

Quarq DZero – 10 years of innovation

Meet DZero, the next-generation platform in power meters - packed with 10 years of technical innovations, plus new features such as MagicZero™ calibration and dual Bluetooth low energy, a simplified product line and revised circuitry. 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 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.
