SRAM Rival AXS Power Meter Crank Arm
The SRAM Rival AXS Power Meter Crank Arm is an easy and affordable way to add power to your SRAM Rival AXS crankset. Simply replace your current left crank arm with the SRAM Rival power meter and you’ll have power on every ride! Featuring an all-new spindle-based design, the power meter sensors are neatly and securely packaged within the DUB spindle for a clean integration, minimum weight and maximum compatibility.
In addition, with Quarq’s proven reliability and accuracy, this crank arm power meter is accurate to 1.5%, so you’ll know your data is always accurate. You also get approximately 400 hours of battery life off of a user replaceable lithium AAA battery. Perhaps best yet, at only $263, it’s one of the most affordable direct force powers meter on the market today!
Key Product Details

Advice From Our Staff:
This is a great way to add power to a SRAM Rival AXS DUB crankset. The Rival power meter is affordable, easy to install and works well. In addition, it’s the only power meter (aside from power meter pedals) that will fit a Rival AXS DUB crank. It has become one of our best-selling power meters. The one consideration is it only measures left leg power compared to some other power meters that measure power from both legs.
Options For This Power Meter
- Crank arm length: 160 mm | 165 mm | 170 mm | 172.5 mm | 175 mm
- Chainline: Regular | Wide
Compatibility
This power meter is compatible with SRAM Rival AXS DUB cranksets. This power meter will NOT fit the older generation Rival GXP or BB30 cranksets. Please see the image below. If you have a Rival GXP or BB30 crankset, we would suggest this article: What power meter will work with my SRAM Rival BB30 or GXP crankset?
Regular vs. Wide
The Rival DUB crankset comes in both Regular and Wide versions. The Regular version fits most road bikes, whereas the Wide version is meant for bikes with larger tires such as cyclocross and gravel bikes.
Here is a quick way to determine which version you need in most cases:
- SRAM Rival DUB 1X – Wide
- SRAM Rival DUB 2X 43/30 – Wide
- SRAM Rival DUB 2X 46/33 – Regular
- SRAM Rival DUB 2X 48/35 – Regular
IMPORTANT – However, if you want to be 100% sure, you would need to pull the cranks off of your bike and view the writing on the spindle. If you have the Regular version, you will likely see the words “DUB” printed on the spindle. If you have the Wide version, you should see the words “DUB WIDE”.

Product arrived in new condition as expected. Easy install and zero issues so far. Great first experience with power meter City especially since no one has the 165mm locally
MikeS (verified owner) –
Great product and even better service. Only issue was installation which turned out to be extremely simple. You tube videos targeted other SRAM power meters. I was hesitant to use the torque required to take out the 8 mm hex bolt but once I found a video to demonstrate how to remove the bolt without destroying the bike, installation took five minutes.

Awesome! Glad you were able to figure it out! Please let us know if there is anything else we can help you with!

Stopped working 15 miles into the first ride. Swapping the battery did nothing and SRAM support is non-existent. Save your money and get a different model.

Hi Derek. Thanks for the review. This can usually be fixed pretty easily. Please see our fix here. Let us know if this doesn’t work – we’re here to help!
Paul Lindewall –
I had to look to YouTube for installation instructions, as there are none included. Once installed, mine didn’t work – cadence readings only, no power. Hours of searching for troubleshooting manuals online didn’t help much. I finally just replaced the battery that came with the unit, which was evidently almost dead on arrival. Now it works.
Power Meter City –
Hi Paul. Thanks for the review. Sorry for any issues caused by a low battery. Unfortunately, as with any electronic device, sometimes the included battery is low. There is really no way for us to know when this is the case but I’m glad you got it sorted. We hope you continue to enjoy it and please let us know if you need anything else.

I had reservations about making this purchase, being that it is spindle based and reads only left-side power, but the price was right so I took the leap. Ordering was easy, the power meter arrived in a few days, and the install was super simple. This product fits perfectly within the SRAM Rival system and easily feeds data to my Garmin head unit &/or smartwatch. I’m not sure what knowing the difference between left & right power generation would make, but just getting power info at all has really improved my training.
Power Meter City –
Thank you, John. Good luck with your training and rides. We hope you will enjoy your new SRAM Rival Crank Arm and please let us know if there is anything else we can help you with! Ride safe!

I took a chance and purchased this crank arm sight unseen, it’s Dub SRAM and easy to install myself. I bought a 175 mm for my mtn bike. The spacing worked for my frame , The power meter paired easily with a Karoo hammerhead 2 . The hammerhead sends data to Strava, love it, never an issue , and I have switched the meter between bikes using BB spacers ,

Great to hear, Don! Thank you for this kind review. We hope you will continue to enjoy your new SRAM crank arm, and if there is anything else we can do, please let us know! Ride safe!
