Madone SL 5 Pro Gen 8 is a lightweight aero road bike that brings elite racing technology to a more approachable price point. Full System Foil tube shaping and 500 Series OCLV Carbon construction save weight where it matters most, while IsoFlow comfort tech lets you ride stronger longer without sacrificing aerodynamics.
