An easy way to add power to your SRAM XX Eagle T-Type crankset!
SRAM XX Eagle AXS Transmission Left Arm Spindle Power Meter
The SRAM XX Eagle AXS Transmission Left Arm Spindle Power Meter is an easy way to add power to your XX Eagle T-Type crankset. Simply replace your current left crank arm with the XX 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 XX Eagle Transmission. The power meter is easy to install and works well. We note however that $643 for left side power is a bit on the more expensive side, but this is mostly due to the fact the power meter comes on SRAM’s top-of-the-line XX Eagle carbon fiber cranks.
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%. However, you must change your chainring to the SRAM XX SL Eagle T-Type Thread Mount version and the smallest chainring size you can run is 32T.
SRAM XX Left Arm Power Meter Compatibility
This power meter is compatible with SRAM XX Eagle SL and XX Eagle AXS Transmission Cranksets (see images below). This power meter will NOT fit the older generation SRAM XX1 Eagle DUB Crank Arms.
