Description

Quarq DFour DUB Power Meter

The Quarq DFour DUB Power Meter benefits from over 10 years of Quarq’s experience in power meters. The result is the ultimate spider-based power meter: one that is accurate, durable and consistent in all conditions. In addition, the DFour platform is now combined with SRAM’s new DUB technology. This means easy part choices, quality materials and a broader compatibility for bottom brackets.

Designed for use with Shimano DURA-ACE 9100 chainrings, the Quarq DFour DUB Power Meter runs for 200 hours on a single CR2032 battery and comes with a full 2-year warranty.
