Quarq DFour AXS 110BCD DUB Power Meter Spider
Description
Quarq DFour AXS 110BCD Dub Power Meter Spider Quarq’s DFour AXS 110BCD DUB Power Meter Spider matches the Shimano Dura-Ace R9100 groupset aesthetically and will also fit the four-bolt chainrings in the Ultegra® R8000 and 105® R7000 ranges. Data on both power per leg and cadence is provided to an accuracy of +/-1.5% for effective training and the spider can receive firmware updates via the SRAM AXS smartphone app. MagicZero technology means that manul calibration isn’t needed as the system checks and recalibrates the power meter when necessary, and even temperature changes or swapping chainrings has no effect on the accuracy. The CR2032 battery can last up to 200 hours and doesn’t require any tools to change.
