The Madone SL 7 Gen 8 is a race-ready bike that offers a lot: Its lightweight frame made of 500 Series OCLV Carbon allows you to ascend easily, while its aero geometry reduces drag on descents and the IsoFlow technology ensures high comfort over long distances. You get an electronic Shimano Ultegra Di2 wireless shifting system for smooth gear changes every time, while carbon wheels, handlebars, and stem save weight and deliver outstanding performance.
