The SRAM XX Eagle AXS Transmission Left Arm Spindle Power Meter utilizes our World stage proven XX crank arm with a subtly integrated power meter to record and deliver live, accurate power readings to your head unit.

We achieve this by utilizing what we call “DUB-PWR”- a unique design that elegantly houses Quarq’s reliable and accurate power measurement inside the DUB crank spindle itself.

Measuring left-side power to calculate total watts, it’s subtle, lightweight, compatible with any chainring setup, and boasts unparalleled battery life.

It is also compatible with the Flight Attendant system, allowing for total connectivity between all AXS enabled components.
