2025 Sram X0 Eagle AXS Transmission Left Arm Spindle Power Meter
SRAMX0 Eagle AXS Transmission Left Arm Spindle Power Meter provides riders with accurate, live power data delivery housed in our most advanced aluminum crankset. The power meter technology is integrated through 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 with robustness in mind.
