SRAM Quarq Power Meter DZero Spider for Specialized Crank | 130 BCD
SRAM Quarq Power Meter DZero Spider for Specialized Crank | LK 130
For more than 10 years, Quarq has developed 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 Quarq DZero Powermeter Spider is compatible with Specialized S-Works Road cranks from model year 2013. A Specialized Lock Ring Tool is required to install.
