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.

 

Key Product Details

Compatibility:

This power meter fits SRAM RED, SRAM Force and Quarq DZero 8-bolt crank arms. It fits both the DUB or GXP versions. It ships with Quarq DZero crank arms unless otherwise specified. Regarding chainrings, it is designed for Shimano DURA-ACE 9100 chainrings. Shimano Ultegra R8000 and 105 R7000 rings also work, however they will not match the shape or color of the power meter as nicely. See Compatibility tab for more information.

Power Measurement:

The Quarq power meter measures power at the spider and is therefore able to measure power from both legs.

Key Features:

Dual-leg power measurement, accurate to +/- 1.5%, lightweight carbon crank arms, 200 hours of battery life, CR2032 user-replaceable battery, ANT+ and Bluetooth compatibility, auto-zero (automatic calibration). See Specs tab for more information.

Advice From Our Staff:

We are big fans of Quarq power meters. They benefit from close to 15 years of Quarq’s experience in power meter technology. It measures power from both legs, is accurate and reasonably priced. Please note, it requires the use of a SRAM DUB bottom bracket.

 

Options For This Power Meter

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

  •  165 mm | 167.5 mm | 170 mm | 172.5 mm | 175 mm

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.

 

Other Versions to Consider

DZero: The DFour you are viewing here works with 4-bolt Shimano chainrings, however if you want to use 5-bolt chainrings, we have the Quarq DZero DUB Power Meter.

Compatibility

Crank arms: The Quarq DFour DUB Power Meter spider fits SRAM RED, SRAM Force and Quarq DZero crank arms. It fits both the DUB or GXP versions. The power meter ships with the Quarq DZero crank arms unless otherwise specified.

Chainrings: The power meter is designed for use with Shimano DURA-ACE 9100 chainrings. Shimano Ultegra R8000 and 105 R7000 rings will also work, however they will not match the shape or color of the power meter as nicely.

The power meter is compatible with Shimano 12-speed chainrings such as DURA-ACE 9200, Ultegra R8100 and 105 R7100, however, they don't match the shape of the power meter spider as nicely. Please see the Questions tab for more information.

Common Questions and Answers

Question: Is the Quarq DFour Power Meter compatible with Shimano 12-speed chainrings?

  • Yes, you can install Shimano 12-speed chainrings on this power meter, however the shape of the chainrings does not match the power meter (please see the image below). This is a cosmetic issue only, but we understand this is important to customers.

    Easy Install, looks great and has never let me down. Often forget its even there. Have on both my BB86 bikes and have been surprised by the durability of the dub BB also.

    • Power Meter City

      Great to hear, Shane! Thank you for taking the time to leave us a great review on your new Quarq DFour DUB Power Meter. Please let us know if there is anything else we can do!

  2. Moristans (verified owner)

    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

  3. Kanwei Li (verified owner)

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

  4. 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!

  7. BikeBeast (verified owner)

    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.
