Quarq DFour DUB Power Meter

The Quarq DFour DUB Power Meter is designed for users of a Shimano crankset that want to step-up their game and start training with power! Featuring a 110 BCD, 4-bolt configuration, the DFour accepts all Shimano road chainrings. However, it is ideally suited for DURA-ACE 9100 rings specifically (for cosmetic purposes). This power meter benefits from over 10 years of Quarq’s experience in power meter technology. Therefore, it is accurate, durable and consistent in all conditions. It also has features such as MagicZero (automatically offsets) and 10K Temperature compensation (stays accurate regardless of temperature changes).

The DZero platform is now combined with SRAM’s new DUB technology. This means easy part choices, quality materials and a broader selection for bottom brackets and chainrings. The power meter runs for 200 hours on a single CR2032 battery and comes with a full 2-year warranty.

Please note, you must pair the Quarq DFour DUB Power Meter with Quarq DZero DUB crank arms and a SRAM DUB bottom bracket.

 

Highlights

Accurate, Durable, Consistent

The DFour benefits from over 10 years of Quarq’s experience in power meter technology.

MagicZero

With MagicZero, the power meter automatically calibrates as you ride. Therefore, you do not need to perform manual offsets!

10K Temp. Compensation

The power meter reads true regardless of the environment and any changes in temperature.

DUB Technology

DUB crank arms and bottom bracket adds durability, simplicity and broad selection.

OmniCal

With SRAM’s OmniCal, you can change chainrings and your power meter stays accurate.

Compatible

You select the chainring, crank arm length and DUB bottom bracket to fit your liking.

Options

Crank arms: 165 mm | 167.5 mm | 170 mm | 172.5 mm | 175 mm

You can purchase the Quarq DFour power meter with or without crank arms. Available crank arms are:

DZero DUB – These are the crank arms that are pictured above and will ship with the power meter unless otherwise specified (they require a SRAM DUB bottom bracket). Unless you need GXP or higher-end SRAM RED crank arms, these are the ones we recommend.

Force GXP – If would like to use a GXP bottom bracket on your bike (Trek BB90 for example), the SRAM Force GXP Crank Arms will work perfectly. Please select ‘No crank arms’ on this page and then add Force GXP Crank Arms to your shopping cart.

RED DUB or GXP – If you are looking for the best SRAM has to offer, the SRAM RED Crank Arms are it (available in both DUB and GXP). The RED cranks are lighter (by about 140 grams) and stiffer than the DZero and Force arms. If you would like to order the power meter with SRAM RED cranks, please select ‘No crank arms’ on this page and then add the SRAM RED Crank Arms to your shopping cart.

 

Compatibility

Crank arms: You must pair the Quarq DFour DUB Power Meter spider with the crank arms listed above and either a SRAM DUB or GXP bottom bracket.

Chainrings: The power meter is designed for use with Shimano DURA-ACE 9100 chainrings. Shimano Ultegra R8000 and 105 R7000 rings also work. However, they don’t match the color of the power meter as nicely.

    Install was very straighforward, from the bottom bracket switch for the DUB crankset, to firing up the SRAM AXS app for the first time. Much thanks to Josh for patiently answering a ton of questions prior to puchase, and to Niel and Power Meter City for the super fast shipping. Couldn’t be happier with my purchase.

    • Power Meter City

    Just works – easy to install, super light, and doesn’t need any calibration. Highly recommended!

  3. chikin2000 (verified owner)

    Great product! However, I’ve done some search, most of those quarq crank arms are weight around 330g, The 170mm quarq crank arm I’ve bought is 476g. what is the reason of the weight difference?

    • Power Meter City

      Hi chikin2000, Thank you for this kind review! You actually have the new version of the Quarq DFour crank arm – which is why the weight is different. We are here if there is anything else we can help you with!

    I purchase the Quarq DFour DUB 175mm power meter and it arrived promptly. I’m going to use it to replace a Stages Dura Ace single side power meter which was eating C2032 batteries every other day. I have other Quarq DFour powermeters and they work excellent and are great for dual sided power. The accuracy and battery life are excellent. At the price it is almost the same as the Stages meter. Just a great deal.

    Looks great, works great, never any complaints about any of my quarq products and the dub spindle seems to be lighter and more adaptable than the GXP power meters i have been using.
