SRAM Crank | Quarq Power Meter DZero 2x11 DUB 52/36 Teeth

SRAM Crank | Quarq Power Meter DZero 2x11 DUB 52/36 Teeth The specialists for power measurement systems from QUARQ have made their DZero and DFour power meters fit for the universal SRAM DUB crank standard. Their lightweight aluminum crankshafts with a diameter of 28.99 millimeters are compatible with the corresponding DUB bottom bracket for all common racing bike bottom bracket standards. The latest generation of Quarq power meters can therefore easily be switched between several bikes. But not only the crank system has changed, the Quarq Spider has also been equipped with new features. 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 that the power meter is optimally calibrated at all times and manual calibration is superfluous. OmniCal and 10K Active Temperature Compensation ensure consistent readings at all times, even when changing chainrings and changing temperatures.
