TREK Madone SL 5 Gen 8

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, but with a more economical OCLV 500 Carbon lay-up and two-piece cockpit with hidden cable routing. It's built to race, with geometry that keeps you quick on the sprints yet in control on fast descents. A Shimano 105 group set keeps the price down while still delivering clean mechanical shifting you can trust.
