Every innovation in Quarq’s next-generation DZero platform is channelled into DFour: 10 years of Quarq advances in power meter technology, plus new features such as dual Bluetooth low energy and ANT+ wireless data transfer, revised circuitry, a new strain gauge design and the new Qalvin BLE app. The DFour chassis pairs with Shimano’s 11-speed Dura-Ace 9000, Ultegra 6800 and 105 5800 chainrings. New DFour91 is designed for Shimano’s Dura-Ace R9100 chainrings. Both use Quarq’s lightweight, sturdy ExogramTM carbon crank arms. GXP and BB30 versions work with every bottom bracket shell, including BBright and BB386EVO. If you already have a power meter with an 8-bolt interface, upgrade using the DFour or DFour91 power meter spider.
