The ultimate spider-based power meter for your SRAM XX1 crankset!
Quarq SRAM XX1 Eagle DUB Power Meter
The Quarq SRAM XX1 Eagle DUB Power Meter 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 Standard chainline configurations.
Key Product Details
Compatibility:
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.
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
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 or Standard 49 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).
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 drive trains?

Question: My frame is super boost. Can I use a 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 a Quarq XX1 power meter?

I’ve run a few of these Quarq XX1’s over the last few years on multiple different bikes. I keep coming back to them because they work flawlessly and are trouble free. PMC was well priced, had easy ability to order the rings/spider/arms all together and they shipped fast. No complaints here.

I bought the Quarq SRAM XX1 Eagle DUB Power Meter setup (along with the matching crank arms) and it shipped out super fast! The customer service here is amazing, I managed to order the wrong thing twice and Josh contacted me before shipping and fixed my mistake on their end. Still got everything within two days of ordering. Thanks!

Bought the Quarq SRAM XX1 Eagle DUB Power Meter for a Yeti SB100 and it works great! Placed an order on PowerMeter City and it shipped out quickly. One thing to note, my Yeti came with a 30 tooth chainring and I wanted to keep 30 tooth as I will be racing the Leadville 100 with this bike, and didn’t want to go any higher than a 30T chainring for that long grueling race! I contacted Quarq, and they said the lowest you can go is 32T due to clearance issues. BUT, Wolftooth makes a 30T 104BCD that has a cutout that allows for clearance. So IT IS possible to keep your 30T with this set up. I’d post a pic if I could, but doesn’t look like you are able to post pics in the reviews. Anyways, great product, and PowerMeter City has great prices, and great customer service. You can’t go wrong.
