Description of Quarq DFour Carbon Power Meter Crank - GXP

DFOUR: DZERO INNOVATION FOR SHIMANO BIKES

Every innovation in Quarq’s next-generation DZero platform is channeled into DFour. The power meter platform combines 10 years of technology advances with new features such as dual Bluetooth low energy and ANT+ wireless data transfer, the new Qalvin BLE app. The DFour power meter is a bolt-on upgrade for Shimano’s 11-speed Dura-Ace 9000, Ultegra 6800 and 105 5800 drivetrains.

  • Designed for Dura-Ace 9000 chainrings. Compatible with Ultegra 6800 and 105 5800 chainrings.
  • Must be paired with a compatible SRAM bottom bracket.
  • ELSA RS power meter owners can upgrade using the DFour Power Meter Spider.
  • Free firmware upgrades with the Qalvin app.

When Quarq set out to build the next generation Quarq power meter, they wanted to build the best-performing power meter for every facet of cycling and triathlon, and for riders at every level. Like its Quarq brethren, the new DFour measures power in the heart of the bicycle — the crankset spider, scientifically proven to be the place for the most accurate measurement. With a new measurement circuit, a revised strain gauge design, improved accuracy throughout the pedal stroke and software advances built into the Qalvin App, DFour represents the state of the art in power meter technology.
