The Madone SL 5 Gen 8 is a lightweight aero road bike that brings elite racing tech to a lower price point. It offers similar aero benefits to the pricier Madone SLR Gen 8 models, but with a more economical OCLV 500 Carbon lay-up and two-piece cockpit with hidden cable routing. A Shimano 105 group set, alloy handlebars and alloy wheels keeps the price down while still delivering clean mechanical shifting you can trust.
