Overview
About this bike
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. It's 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. - Revolutionary Full System Foil aero tube shapes redefine what fast looks like and help optimize aerodynamics around the whole bike - 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 Shimano's workhorse groupset – 105 - Lightweight, race-focused IsoFlow comfort tech helps you ride stronger longer without sacrificing weight or aerodynamics
