      SRAM XX1 Eagle DUB crank | Quarq DZero Power Meter

      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 DUB technology not only simplifies the combination of crankshaft and bottom bracket, it also ensures a higher durability of the inner bearing. SRAM DUB cranks have a uniform shaft diameter of 28.99 millimeters. Through various variants of the completely redesigned and better sealed DUB bottom bracket, the cranks are compatible with all common bottom bracket housings. The aluminum crankshafts have also been redesigned, reducing the weight of the DUB crank sets over their predecessors.

      Through the use of the Carbon Tuned manufacturing process, the wall thickness of the XX1 Eagle DUB crank could be chosen at all points, so that it has a very high rigidity and yet is an absolute lightweight. Matching chainrings with 30 to 38 teeth can be found in our shop.
