Sram: X0 Eagle AXS Transmission Power Meter Crankset 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.FEATURESInnovative DUB-PWR design allows for lightweight, subtle Quarq power integration.Compatible with Flight AttendantUnique, groundbreaking design integrated with the lightest aluminum crankset on the market.+/- 3% accuracyLong battery life (400+hours)User replaceable AAA lithium batteryWaterproof (IPX7 waterproof to 1 meter for 30 minutes)30-34T ringsCan be run with chainring bash guards SPECIFICATIONSSpeeds: 12BB Compatibility: All SRAM MTB WIDE DUB BBsChainring Size: 32TCrank arm length: 165mm, 170mm, 175mmChainline: 55.0mmBB Spindle Interface: DUBChainring material: AluminumGuard: CompositeBolt Circle Diameter (BCD): Direct Mount (DM)Crank arm material: CarbonColor (Crank arm): BlackPower meter: YesPower Meter Type: Spindle
