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 layup and two-piece cockpit with hidden cable routing. Its built to race, with geometry that keeps you quick on the sprints yet in control on fast descents. A Shimano 105 groupset keeps the price down while still delivering clean mechanical shifting you can trust.

- A more economical 500 Series OCLV Carbon frame and new tube shaping shave weight where it matters most to help you fly up climbs
- You get clean and reliable shifting without breaking the bank with Shimanos workhorse groupset – 105
- Lightweight, race-focused IsoFlow comfort tech helps you ride stronger longer without sacrificing weight or aerodynamics
