Availability: Out of stock

Madone SL 6 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, but with a more economical OCLV 500 Carbon layup and two-piece cockpit with hidden cable routing. It's built to race with geometry that keeps you comfortable on the climbs and perched for the attack. A Shimano 105 Di2 electronic groupset keeps the price down without sacrificing lightning-fast electronic shifting. Plus, it's topped off with carbon wheels for extra lightweight performance.
