SRAM XX1 Eagle crank | Quarq DZero PowerMeter BB30

For the past 10 years Quarq developed performance measurement systems for athletes who want to leave nothing to chance in training. In the DZero PowerMeter platform Americans could incorporate all their experience and integrated the latest technical standards.

The DZero PowerMeter continue to rely on a spider-based performance measurement. Since this system performance measures there where it is rendered and the power is measured by both legs, this system ensures a very high accuracy. Externally changed only in detail, the DZero PowerMeter but have a completely redesigned interior. Not only the instrumentation is new, even the arrangement of the strain gauges has been further optimized. The result is an even more accurate power measurements at every stage of a turn of the handle and an improved measurement accuracy in temperature. Thus, the values must be less corrections via the internal software. Another important new feature is the data transmission via Bluetooth Low Energy standard, in addition to transmitting the ANT + standard. Thus, the DZero PowerMeter can be paired with almost all available in the market cycle computers and smartphone apps. To upload firmware updates and perform system diagnostics, Quarq has developed the Qalvin app for IOS and Android.

The Sram Eagle 1 subject PowerMeter with 104 mm bolt circle is ideal for SRAM 1x11 and 1x12 X-Sync chainrings. These keep the chain without chain guide reliably on the chainring. To BOOST rear hub to ensure optimal chain line in combination with 12x148 mm, there is the spider in a BOOST variant. The lightweight and robust XX1 Carbon Tuned crank arms are available in 170 mm and 175 mm length.
