SRAM X0 Eagle AXS Transmission Left Arm Spindle Power Meter

The SRAM X0 Eagle AXS Transmission Left Arm Spindle Power Meter is an easy way to add power to your X0 Eagle T-Type crankset. Simply replace your current left crank arm with the X0 power meter and you’ll have power on every ride! Featuring SRAM’s DUB-PWR design, the power sensors are neatly and securely packaged within inside the DUB crank spindle itself. This results in a clean integration, minimum weight and maximum compatibility. The power meter gets 400+ hours of battery life off of a lithium AAA battery and is fully compatible with SRAM’s Flight Attendant.

Advice From Our Staff:

This is a great, easy way to add power to a SRAM X0 Eagle Transmission. The power meter is affordable, easy to install and works well. 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 lengths: 165 mm | 170 mm | 175 mm


Other Versions to Consider

SRAM XX Eagle AXS T-Type Power Meter Spider: We also sell the SRAM XX Eagle AXS T-Type Power Meter Spider. This power meter will measure power from both legs and is also slightly more accurate at +/- 1.5%.

    I really like Power Meter City and this has nothing to do with them! BUT… this power meter has been a disaster for me. Original was reading very low (resulting in power TSS in rides down 30-40%, consistently). Wasted weeks troubleshooting (VERY slowly) with Quarq/SRAM. After over a month, a replacement was finally sent. And… same problem. I am giving up. Perhaps “you get what you pay for” is the root cause problem, I don’t know. $326 wasted. I’ll have to buy a new/different/better power meter.
    Note: This is the same tech as the single-sided SRAM Rival road power meter, I now understand. And I found a Shane Miller YouTube video from him a few years ago where he had to use other accurate power meters and a big slope adjustment to make that power meter accurate… sure sounds similar…
