Effortless performance. Effortless perfection. We refined every part of RED to create effortless one-finger braking, smooth front shifting, fully wireless connectivity, and expanded gearing choices to fit every rider. We packed in every feature we could, like accurate and reliable power measurement, new shift points, and more brake adjustability, while still shaving g off every component to bring you the lightest electronic groupset ever. Riding isn’t effortless. RED is.
