SRAM XX Eagle AXS Transmission Left Arm Spindle Power Meter D1

The SRAM XX Powermeter crank arm is compatible to the innovative Eagle Transmission drivetrain and uses precise Quarq power measurement technology to give riders an advantage over the competition. Elegantly and inconspicuously hidden in the crank shaft, the DUB-PWR measuring unit collects the data that athletes need for their progress. The crank arm itself is not only incredibly light thanks to the use of carbon fiber, but also guarantees incredible strength and maximum stiffness in combination with its foam core.
