Quarq DZero DUB Power Meter

The Quarq DZero DUB Power Meter benefits from over 10 years of Quarq’s experience in power meter technology. The result is the ultimate spider-based power meter: 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).

In addition, 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.

Power Measurement:

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

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

BCD: BCD is bolt chain diameter. This is a measurement of the size of the crank spider. Most 50/34T and 52/36T rings use a 110 BCD, whereas 53/39T use a 130 BCD. If you are not sure what your BCD is, please contact us so we can help.

• 110 or 130

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.

Compatibility

Crank arms: The Quarq DZero 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 compatible with most 10- and 11-speed, 5-bolt chainrings. We suggest using SRAM X-Glide Chainrings for all 11-Speed applications.
