Every innovation in Quarq’s next-generation DZero platform is channelled into DFour.
The power meter platform combines 10 years of technology advances with latest features such as wireless Dual Bluetooth Low Energy and ANT+ data transfer as well as the compatibility to the Qalvin BLE app.
When Quarq set out to build the DFour, they wanted to build the best-performing power meter for every facet of cycling, 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.
