Experience the effortless performance of the SRAM RED AXS Groupset. Every part has been refined to deliver one-finger braking, smooth front shifting, and fully wireless connectivity. With expanded gearing options, accurate power measurement, new shift points, and enhanced brake adjustability, this groupset provides everything needed for top-tier cycling. Despite the feature-rich design, it's the lightest electronic groupset ever. The aftermarket groupset includes a rear derailleur, front derailleur, shift-brake controls, chain, disc brake calipers, rotors, battery charger, and Hammerhead Karoo. Riding isn’t effortless, but RED makes it feel that way.
