    The DZero from Quarq accurately captures your power output readings via Bluetooth low energy or ANT+ wireless data transfer and enables you to view them live on your compatible cycle computer or smartphone. This model is designed for frames with BB30 bottom brackets, but it also comes with the washers required for use in BB386 Evo frames.

They also have a waterproof rating of IPX7 to ensure you can use them in all weather conditions and obtain flawless performance and precise readings on every ride.

    Easy to Use

    Manual and automatic zeroing features mean that Quarq power meters really are set and forget and the chainrings are easily replaceable should your bike, discipline or ability change.

    • Direct-force Technology: Quarq power meters use their patented direct-force technology to precisely measure your physical performance throughout your ride. Their meter is located in the crankset, the heart of the bicycle. Because it gathers data from both legs, and it's located at the precise point where muscle energy is converted to forward movement, the power meter spider is the most accurate place to gather power data.
    • 10K Temperature Compensation: Eliminates variables caused by heat and cold to provide an unwavering record of your performance through all conditions.
    • IPX7 waterproof rating: To reach this high level of waterproofness, these cranks have been submerged in a water depth of 1000mm for a period of 30 minutes, and has repeatedly worked flawlessly.
    • Qalvin BLE with Bluetooth: For iOS and Android. With any smartphone you can set zero offset, check battery, run diagnostics and update firmware, all for free.
    • OmniCal: DZero also features Quarq's OmniCal design which enables you to change chainrings without affecting accuracy.
    • AxCad: The DZero cranks have an integrated accelerometer cadence, so there's no additional magnet to add to the crank arm.
