2025 Madone SLR 7 Gen 8
The Madone SLR 7 Gen 8 is an ultra-aero and featherlight road bike that's built to race. Its 900 Series OCLV Carbon frame is not only aerodynamic, but also ultra-light for flying up climbs. Lightweight IsoFlow frame technology means that the Madone doesn't sacrifice comfort for speed. To give you every aero advantage, the Madone SLR comes with RSL Aero Bottles and Cages that further reduce drag. This build comes ready to win with a Shimano Ultegra Di2 group set, carbon wheels and a Trek Aero RSL one-piece carbon bar/stem.
