Effortless performance meets effortless perfection. Every part of RED has been refined to deliver one-finger braking, smooth front shifting, fully wireless connectivity, and expanded gearing options to suit every rider. It incorporates every possible feature, including accurate and reliable power measurement, new shift points, and enhanced brake adjustability, all while reducing weight on every component to create the lightest electronic groupset ever. Riding isn’t effortless, but RED makes it feel that way.
