      SRAM RED Crank | Quarq Power Meter DZero BB30 | BB386 | LK 130 mm

      For 10 years, Quarq has been developing performance measurement systems for athletes who do not want to leave anything to chance in training. In the DZero Powermeter platform, the Americans incorporated their entire experience and integrated the latest technical standards.

      The DZero power meters continue to rely on a spider-based power measurement. Since this system measures the power where it is provided and the power of both legs is measured, this system ensures very high measurement accuracy. Outwardly only changed in detail, however, the DZero power meters have a completely reworked interior. Not only is the measurement technology new, but the arrangement of the strain gages has also been further optimized. The result is an even more accurate power measurement in each phase of a crank revolution and improved measurement accuracy with temperature fluctuations. Thus, the values ??need to be corrected less via the internal software. Another important new feature is the data transmission via Bluetooth Low Energy Standard, in addition to transmission in the ANT + standard. Thus, the DZero power meters can be coupled with almost all available on the market bike computers and smartphone apps. To upload firmware updates and perform health checks, Quarq has developed the Qalvin app for iOS and Android.

      The SRAM Red Exogram crank is manufactured entirely in hollow construction and thus guarantees very high stiffness values ??at extremely low weight.
      Thanks to the compact design of the Power Meter, the system weight is very low and offers plenty of space on oversized frames. For the release of the revolutionary, wireless Sram eTap Group, the Americans of the RED Power Meter cranks have given a visually fitting design.


      - 10K Active Temperature Compensation
      - Wireless data transmission via Bluetooth Low Energy or ANT +
      - Chainring changes do not require recalibration and have no influence on the measuring accuracy
      - Cadence measurement via acceleration sensors (no additional magnet required!)
      - waterproof construction according to IPX7 standard
      - LED power indicator always informs about battery level
      - 200 hours of operation (tool-less battery change according to CR2032 standard)

      - Power balance
      - +/- 1.5% measurement accuracy
