Product information "Quarq DFour91 power meter"

The manufacturer Quarq launches a new Quarq DFour91 power meter. With the Quarq DFour 9100 power meter you have the possibility to use asymmetric 4-hole chainrings of the Dura Ace R9100 and Ultegra R8000 series. The Quarq DFour 9100 is compatible with the BB386EVO and BBRight frames. The Quarq DFour91 power meter convinces with its quality and measuring precision.

As with the Quarq DFour power meter, the measurement technology is integrated in the Spider. The Quarq DFour 9100 power meter can also determine a Li/Re-balance using several strain gauges. This means that your performance is measured separately from the right and left leg. This will give you the opportunity to determine a possible dysbalance. Your power consists of the torque and the cadence (angular velocity). With the Qalvin software you can evaluate your measured values and create a targeted and effective training plan.

TheQuarq DFour 9100 power meter is available in different crank arm lengths (162.5 - 177.5 mm) and axle standards (GXP, BB30). The crank arms of the DFour power meter are made of light Exogram Carbon.

You can connect the Quarq DFour 9100 power meter to your bike computer or smartphone via ANT+ and Bluetooth Low Energy connection. The DFour 9100 is powered by a battery and has a battery life of approximately 200 hours. The battery (button cell) can be changed easily and quickly.
