The QUARQ DFour DUB power meter carbon crankset is composed of two highly moulded carbon crankarms, a DUB axle and the DFour DUB power meter spider. It is your entry into the world of performance measurement - as long as you ride with your Road Dura Ace R9100, Ultegra R8000 or 105 R7000 chainrings. This light, strong and elegant crankset combines the clever DUB platform with the DZero power meter technology, which has been proven over many years.
