Every innovation in Quarq’s next-generation DZero platform is channeled into DFour. It embodies 10 years of Quarq technology advances with new features such as dual Bluetooth low energy and ANT+ wireless data transfer, the new Qalvin BLE app and compatibility with BB30 bottom brackets. Quarq power meters use their patented direct-force technology to precisely measure your physical performance throughout your ride. Their meter is located in the crankset, the heart of the bicycle, and because it gathers data from both legs, and it's located at the precise point where muscle energy is converted to forward movement, the power meter spider is the most accurate place to gather power data. 10K Temperature Compensation Eliminates variables caused by heat and cold to provide an unwavering record of your performance through all conditions. Built to Last An IPX7 waterproof rating, an easy-to replace CR2032 battery, a 2-year warranty, free firmware updates and acclaimed worldwide support. Easy to Use Manual and automatic zeroing make Quarq power meters truly set and forget. The chainrings are replaceable should your bike, discipline or ability change. Qalvin BLE with Bluetooth For iOS and Android. With any phone you can set zero offset, check battery, run diagnostics and update firmware. Free. Other Features DFour also features OmniCal (change chainrings without affecting accuracy) and AxCad (accelerometer cadence – no magnet).
Built on to a Shimano's top-of-the-line Dura-Ace R9100 non-drive side crank arm, the Stages Gen 2 sensor is individually calibrated to ensure its accuracy.
