Accurate, reliable power measurement is practically a requirement these days, and the Quarq SRAM Apex AXS crankarm power meter upgrade is the easiest way to get precise power numbers. With the tech hidden inside the DUB spindle, it fits almost any bike while remaining stealthy.
AXS is SRAM's new bike component integration system that connects electronic bicycle components and software. The SRAM AXS app allows riders to see battery status, change component behavior, personalize controls, get maintenance reminders, and update firmware.
DUB-PWR takes Quarq's reliable and accurate power measurement and elegantly houses it inside the DUB crank spindle for compatibility with any chainring setup, measuring left side power to calculate total watts. It's lightweight, invisible and attainable.

Bought this as an upgrade for my gravel bike. I was shopping for power meter pedals but the price of this Spindle system was just too good to beat.
SRAM doesn't really provide any installation instructions and the one video on YouTube was semi helpful but it didn't go into any detail. Make sure that if you have a spacer, to transfer it to the new spindle. I didn't even notice it was there on the original spindle so I had to remove it and install it all again! I also had some issues with a flimsy plastic cap on the BB so keep an eye on that when you do the install.
Once installed though, it has been awesome. Only complaint have been that the calibration step before each ride is kind of annoying and I've had it randomly stop communicating to my Garmin after a cafe stop one time but it finally reconnected after a few miles.
Accuracy seems decent compared to my Zwift trainer and pairing it to my Garmin Edge was super easy.
If you have a bike with Apex, it's a great upgrade to make to get more ride data!
I bought this as an upgrade for my Cervelo Aspero with mechanical Apex. Had to change out the BB as well since going from GXP to DUB. Overall very happy with the swap! I have done a few rides so far and it is great having the power to gauge my efforts on rides. I have even done a few TrainerRoad workouts outside with ability to watch power.
I was very glad to find this fit on my 2023 Trek Checkpoint with SRAM Apex groupset mechanical. I really wanted a power meter that was not $500 pedals. Pretty easy to install if you have enough torque to remove the cranks!
