Quarq DFour DUB crank set

The Quarq DFour is designed for the Shimano  10 and 11-speed chain rings. It is compatible with the Dura-Ace 9100, the Ultegra R8000 and the 105 R7000 chain rings.

With an accuracy of ± 1.5% the Quarq DFour can compete with any other proven power meter system in the market. In addition it features a left-right-power-distribution analysis (Power Balance™).

To be unaffected by changing conditions, Quarq equipped it’s DFour power meter with an active temperature compensation. Furthermore, it is waterproof, fulfilling the IPX7 requirements. No external magnet for cadence measurement is required, as cadence is determined internally, using acceleration sensors.

The Quarq DFour is powered by a regular CR2032 battery, which lasts for at least 200h of operation. No tools are required to change the battery, making it highly user friendly.

Thanks to dual band wireless technology (ANT+ and Bluetooth Smart), the Quarq DFour is compatible with all common head units and cycle computers.

The Quarq power meter crank set is equipped with the SRAM DUB spindle. The Bolt Circle Diameter is 110 mm.

Please note that chain rings are not included in this offer.
