Madone SL 5 Gen 8 is a lightweight aerodynamic race bike that makes elite technologies accessible. It offers similar aerodynamic benefits to the more expensive Madone SLR Gen 8, but with a cheaper 500 OCLV Carbon layup and a two-piece cockpit with invisible cable routing. It is designed for racing thanks to a geometry that favors speed in sprints but allows you to maintain control on fast descents. A Shimano 105 groupset is extremely affordable, offering a clean and reliable mechanical solution.
