The Madone SL 6 Gen 8 is a lightweight aero road bike that brings elite racing tech to a lower price point with a more economical OCLV 500 Carbon lay-up than its SLR sibling. A Shimano 105 Di2 electronic group set gives you lightning-fast electronic shifting and pairs with alloy handlebars to keep the price down. Plus, it's topped off with carbon wheels for extra lightweight performance.
