Hammarsratta esiosa kinnituskronstein võimsuse mõõtjaga SRAM XX1 Eagle AXS Boost DUB Quarq DZero

QUARQ performance measurement specialists have made their DZero and DFour powermeters fit for the universal SRAM DUB crankset. Their light aluminum crankshafts with a diameter of 28.99 millimeters are compatible with the corresponding DUB bottom bracket for all common road bike bottom bracket standards. The latest generation of Quarq power meters can be easily changed between several bikes.But not only the crank system has changed, also the Quarq Spider has been equipped with new features. Thus, the latest generation is compatible with the SRAM AXS App, with which firmware updates and other settings can be made. The new MagicZero function ensures optimum calibration of the power meter at all times and manual calibration is superfluous. OmniCal and 10K Active Temperature Compensation ensure consistent readings even with chainring changes and changing temperatures.The XX1 Eagle DUB 1-speed power meter with 104 mm bolt circle diameter is best suited for SRAM 1x12 X-Sync 2 chainrings. These keep the chain reliably even without chain guide on the chainring. In order to ensure an optimal chain line in combination with 12x148 mm BOOST rear hubs, the Spider is also available in a BOOST version.
