Crafted from our proprietary C:62® carbon using our Advanced Twin Mold manufacturing process, the Reaction C:62 leaves nothing on the table in pursuit of low weight, exceptional speed and precise handling. There's a short rear end with Boost thru axle, a tapered head tube and Agile Ride Geometry. Taken together it all adds up to a lively, responsive ride feel. Slim seatstays and a narrow 27.2mm seatpost help keep you comfortable for longer, even when you're giving it your all. And internal cable routing reduces maintenance, so you can spend more time riding and less time wrenching.
Featuring advanced quality composite material, the Defy Advanced is built with a special carbon material layout to give it an efficient, high-performance ride quality that helps you discover new limits of endurance. The D-Fuse seatpost and handlebar system also help reduce road vibration, adding to its smooth, compliant feel on the road. Giant WheelSystem wheels and tubeless tires enhance speed and efficiency. And for added control, it has built-in flat-mount disc brakes and 12mm thru-axles.
