Market: With the new DZero-based power meters from Quarq, the aim is to increase the compatibility of the power meters in order to give even more cyclists the opportunity to use a high-quality power meter. With the new models DZero Specialized and DFour91, the Quarq Spinder can now also be used with the new S-Works carbon cranksets and the Shimano Dura-Ace R9100.
With over 10 years of experience, Quarq has grown together with SRAM to become a real force in power measurement technology. Both models come with features such as dual Bluetooth Low Energy and ANT+ wireless data transmission, Quarq's latest measurement technology and the Qalvin BLE app. There's also an AxCad accelerometer for cadence and a 2-year warranty. The easily replaceable CR2032 battery offers a great advantage. The power meters are manufactured at Quarq's ISO 9001 certified facility in Spearfish, USA, where the PowerMeter, ShockWiz, Qollector and the QuarqNet and QuarqRace Intelligence software platforms are manufactured.
Quarq DFour91 for Shimano Dura Ace R9100
Designed specifically for Shimano's Dura-Ace R91 series, the Quarq DFour9100 Power Meter brings Quarq's new DZero platform to Shimano's latest groupset. The GXP and BB30 versions are compatible with every popular bottom bracket including BBright and BB386EVO. If you already have a power meter with the 8-bolt interface, you can update it with the DFour91 Spider.
