Madone SLR 7 Gen 8 is an aero, featherlight road bike built to race. Its 900 Series OCLV Carbon frame cuts weight and adds aero gains, while IsoFlow technology boosts comfort without sacrificing speed. It's race-ready with a wireless 2x12 Shimano Ultegra Di2 groupset, Bontrager Aeolus Pro 51 wheels, a Trek Aero RSL one-piece bar/stem, and RSL Aero Bottles and Cages for added drag reduction.
