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.
