Description

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.

Compatible with Shimano Chain Rings
The Dura-Ace R9100 sprockets fit best on this power meter. However, you can also place the Ultegra R8000 and 105 R7000 sprockets on it without affecting the measurement results.

Rigid and light crank arms
The power meter is a spider to be placed on Quarq Dub crank arms. These carbon crank arms have a low weight and a high stiffness. To mount these crank arms you need a Sram Dub bottom bracket.

Exceptional quality / price ratio

- Denis 13 October 2021

I am very satisfied with the purchase, the quarq dfour power meter is very easy to install, accurate in measuring and also easy to set up. It is also possible to update the firmware with using the sram mobile app It is very difficult to find something so efficient at an equally cheap price, at this figure it is a best buy. Recommended do not miss it !!!
