Description
With this Quarq Dub DFOUR Dura Ace R9100 bundle, you get a strong, lightweight and high performance double-sided power meter. This bundle consists of Quarq crank arms with Dub fitting, the Quarq Dfour power meter spider and possibly Dura-Ace sprockets.
More than ten years of experience
The power meter incorporates ten years of experience that Quarq has with power meters. This means that the chance of malfunctions is further reduced and the power meter gives strong, stable and reliable values. For example, this power meter has Quarq MagicZero technology, with which the power meter calibrates during cycling. It also automatically adjusts itself to changing temperatures, so you always have reliable data. As a result, the power meter has a deviation of only 1.5%.
The power meter is also weatherproof and has a waterproof rating of IPX7.
