The SRAM X0 Eagle AXS Transmission Power Meter Crankset is a complete aluminum crankset with power measurement built into the DUB spindle. SRAM calls the arrangement DUB-PWR, placing Quarq sensing hardware inside the spindle rather than in a spider or an external pod. It measures left-side power and calculates total watts for display on a head unit.
Both crank arms, the spindle and a 32T T-Type direct mount chainring are supplied together, so this is a full crankset rather than a left arm upgrade kit. The chainring mounts on an eight-bolt interface at a 55 mm chainline. A user-replaceable AAA lithium cell gives over 400 ride hours, accuracy is quoted at plus or minus three percent, and Flight Attendant is supported.
