  • The Quarq DZero power meter is included in this years Editor’s Choice for the simple reason it is reliable, durable and with many purchase options one of the most integrateable power meters on the market.

    The new Quarq DZero power meter is named after the DZero experiment, according to Quarq. That experiment was one of science’s most accurate and innovative projects to detect subatomic particles moving at the speed of light – so Quarq is hoping for great things after such a name check.

    A new measurement circuit along with revised strain gauge design for the Quarq DZero Power meter is to improve accuracy to within 1.5%. I tested this against the Wahoo Kickr and found it to be three to four watts above what the Kickr was reading during the same effort.

    This would account for drivetrain watt loss and proves that the reading is fairly accurate. I didn’t experience any reading drop outs or any spikes during rides, efforts or post analysis either.

    Coin cell battery is well housed

    Quarq DZero is easy to install to when ordered with your preferred bottom bracket standard but you’ll need the right removal kit as SRAM and Shimano are different standards.

    I’ve tested this power meter over 2000kms now, the single coin cell battery is still good and I haven’t experienced and problems so far. The power meter still shows a green light and connects to my Garmin easily.

    To keep the Quarq Dzero power meter functioning as it should you can download the Qalvin app. This allows to update firmware update, run diagnostics and check battery voltage details another nice touch of the entire system. It’ll help if there is an update from Garmin or other units so everything works together as it should.
