Madone SL 7 Gen 8 is a race-ready road bike engineered to deliver performance without compromise. It strikes the perfect balance between speed, comfort, and value.
Built with a lightweight 500 Series OCLV Carbon frame, it climbs with confidence while its advanced aero geometry reduces drag for maximum efficiency. IsoFlow technology enhances comfort without sacrificing speed—so you can push harder, longer.
A precise Shimano Ultegra Di2 wireless drivetrain delivers fast, seamless shifting, while carbon wheels and handlebars keep the ride responsive, efficient, and race-day ready.
