SRAM left-side crank arm and powermeter axle XX D1 174mm 55mm DUB MTB Wide

The XX Eagle AXS Transmission Left Arm Spindle Power Meter utilizes Srams World stage proven XX crank arm with a subtly integrated power meter to record and deliver live, accurate power readings to your head unit. Sram achieves 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 unbeatable battery life. It is also compatible with the Flight Attendant system, allowing for total connectivity between all AXS enabled components. No-compromise, no-fuss data delivery giving you an edge over the competition.
