Description

The QUARQ DFOUR DUB Power Meter Crankset helps you reach new goals thanks to its precision, reliability and durability.

Designed to fit Dura-Ace R9100 and Ultegra R8000 chainrings, it is paired with Quarq DUB cranks and requires a SRAM DUB bottom bracket for installation. Bluetooth Low Energy and ANT connectivity ensures fast and reliable data transfer. 

MagicZero technology automatically recalibrates the sensor in real time, eliminating the need for manual calibrations. Thanks to AxCad, no cadence magnet is required. OmniCal allows chainrings to be swapped without affecting measurement accuracy, which remains reliable at +/-1.5%, measuring both legs. Battery life exceeds 200 hours with a tool-free replaceable CR2032 battery.
