AERO SRAM RED AXS 1x12 Speed D1 QUARQ ROAD POWERMETER DUB Crankset

In certain disciplines, the single-ring drivetrain reigns supreme. Championing simplicity, strength and durability, the SRAM RED 1 AXS™ power meter meets the demands of triathletes, time trialists and cyclocross racers. The power meter features improved aerodynamics thanks to direct mount aero chainrings with fully integrated power, and the tighter gearing range is perfect for racing and flatter terrains.
