Quarq SRAM XX1 Eagle DUB Power Meter Crankset
The Quarq SRAM XX1 Eagle DUB Power Meter Crankset is the ultimate spider-based power meter for your mountain bike: accurate, durable and consistent in all conditions. The power meter comes loaded with features such as MagicZero, whereby it automatically calibrates (offsets) as you ride. You also get 10K Temperature compensation which ensures the power meter stays accurate regardless of changes in temperature. The XX1 power meter runs for 200 hours on a single CR2032 battery and comes with a full 2-year warranty.
This power meter works with SRAM XX1 Eagle DUB 8-bolt cranksets. It comes in both Boost and Super Boost chainline configurations.
Key Product Details
This power meter works with SRAM XX1 Eagle DUB 8-bolt cranksets. Most bikes come with SRAM 3-bolt cranksets, so it’s important you confirm which version you have. If you have the 3-bolt version, you will need to purchase new 8-bolt cranks, as listed on this page, along with your power meter. This crankset also requires the use of a SRAM DUB bottom bracket. See Compatibility tab for more information.
The Quarq power meter measures power at the spider and is therefore able to measure power from both legs.
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
Chainline: This refers to your bike’s chainline spacing. Most modern mountain bikes are boost 52 mm. If you are unsure, please contact us and we will do our best to help.
- Boost 52 mm | Super Boost 55 mm
Please note – some bikes have super boost 56.5 mm chainlines. Unfortunately, this crankset is not intended for those bikes as the widest chainline you can achieve is 55 mm.
Crank arms: You can purchase the power meter with or without crank arms. Available sizes are:
- 165 mm | 170 mm | 175 mm
Chainrings: You can purchase the power meter with or without chainrings. Available sizes are:
- 30* | 32 | 34 | 36 | 38
*The Quarq SRAM X-SYNC 2 12-Speed Chainring is not offered in a 30T. Therefore, for 30T applications, we ship a Wolf Tooth Components 1x 104 BCD MTB Chainring. The WT ring is compatible with 9-, 10-, and 11-speed chains. It is also compatible with 12-speed SRAM and 12-speed KMC chains (not compatible with Shimano 12-speed chains).
Other Versions to Consider
SRAM XX Eagle AXS T-Type Power Meter Crankset: We also sell the SRAM XX SL Eagle AXS T-Type Power Meter Crankset and the SRAM XX Eagle AXS T-Type Power Meter Crankset. They are also dual-sided power meter cranksets with carbon fiber cranks, however they use a SRAM Thread Mount power meter spider. They are compatible with both T-Type and non-T-Type SRAM Eagle 12-speed drivetrains and are slightly more affordable with prices starting at $950.
XX1 Eagle DUB Power Meter Crankset Compatibility
Crankset: This power meter works with SRAM XX1 Eagle DUB 8-bolt cranksets. Please see the image below. Most bikes come with SRAM 3-bolt cranksets, so it's important you confirm which version you have.
If you have the 3-bolt version, you will need to purchase new 8-bolt cranks, as listed on this page, along with your power meter. Please also note, this crankset requires the use of a SRAM DUB bottom bracket.
Note - if you have 3-bolt cranks and don't want to replace them for the 8-bolt version, we do sell a different power meter that will fit your 3-bolt cranks. Please contact us for information on that option.
This power meter does not fit Cannondale bikes with an Ai offset.
Chainrings: This power meter requires a 104 BCD 4-bolt chainring MTB chainring (which is different than the direct mount chainrings found on many SRAM MTB cranksets). If you don't already have a 4-bolt chainring, we offer several different MTB chainrings to choose from. In most cases, we recommend the Quarq SRAM X-SYNC 2 12-Speed Chainrings for best performance (also available on this page).

Common Questions and Answers
Question: I see that SRAM does not provide a 30T chainring option for this Quarq XX1 power meter. Is the Wolf Tooth 30T Chainring you offer compatible with 12-Speed drivetrains?
- Yes, the Wolf Tooth chainring is compatible with 9-, 10-, and 11-speed chains. It is also compatible with 12-speed Eagle and 12-speed KMC chains (not compatible with Shimano 12-speed Hyperglide+ chains).
Question: My frame is super boost. Can I use this Quarq power meter?
- In most cases, yes you can. You just need to order the power meter with the Super boost 55 mm cranks. Please see our article for more information: My frame is super boost. Can I use a Quarq power meter?
Question: What is the smallest chainring I can use on this Quarq XX1 Power Meter?
- The smallest chainring that typically fits on a Quarq Power Meter is a 32T round chainring or a 34T oval. However, in many cases you can also install a 30T round or 32T oval. You can find out more information in this article: What is the smallest chainring I can use on the Quarq XX1 Power Meter?
Question: Can I use this power meter with the new Eagle Transmission T-Type drivetrain?
- Unfortunately no. This is because SRAM does not make a T-Type 104 BCD chainring that fits this power meter.
Question: What is the difference between this power meter crankset and the new SRAM XX SL Eagle AXS Transmission Power Meter Spider Crankset?
- Both of these MTB crankset power meters measure dual-leg power, feature 8-bolt carbon fiber crank arms and are compatible with SRAM DUB Bottom Brackets. However, there are several differences as well. We recommend the following article for a full comparison: Quarq XX1 Eagle DUB vs SRAM XX Eagle AXS T-Type Power Meter Crankset Comparison.
