Quarq Dzero Power Meter Spider Assembly for Specialized
Boasting excellent efficiency and improved accuracy, Quarq's Dzero Power Meter pairs innovative AxCad technology and Power Balance. Quarq's power meter eliminates the need for magnets, enabling excellent accuracy and efficiency in synchronised measurements of cadence and left-right wattage. A more convenient alternative for bikes where it's difficult to install a magnet.
The use of the OmniCal tech and 10K Active Temperature Compensation makes this power meter the most efficient and easiest to use. Offering improved accuracy over a wider range of conditions, the 10K Active Temperature Compensation uses more than 10,000 data points relieving software changes when it comes to temperature. Whilst OmniCal's independent power measurement maintains accuracy when changing chainrings.
With 200 hours of battery life, this power meter invites you to go on longer rides with less worry. Using CR2032 batteries, the battery is changeable without tools. And with the use of Quarq's digital wrench, the Qalvin smartphone app, you can easily maintain your power meter with free firmware updates, battery readings, calibrations and diagnostics.
With less to think about, the power meter offers great compatibility across the range, with the ability to connect to ANT+ or Bluetooth.
