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. Stages produce power meters that both avid amateurs and professionals at the top of their game can trust. Reliable Readings In All Conditions To ensure consistency of measurement, Stages introduced a world-first feature to its power meters. This feature is called “Active temperature Compensation” and it is built in as standard to account for sudden temperature changes, which if not accounted for, would result in false and inaccurate data.
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.
