Quarq is as well-known for its software technology as it is for its power meters, and this attention to detail shows in all its products. Not only is the Dzero run through rigorous testing to ensure accuracy at all temperatures (surprise: not everyone does this), but the company spends a lot of time ensuring its products—even its old ones— stay on the cutting edge with constant and seamless firmware updates via an excellent companion app. At the same time, the Dzero boasts features like a magnet-less cadence sensor, ±1.5-percent accuracy, and a good value on dual-leg sensing technology—as well as the data that comes with it.
