Trek Madone SL 5 Gen 8 Road Bike
Couldn't load pickup availability
Trek Madone SL 5 Gen 8 is built to keep the pace high when the gradient changes. Full System Foil aerodynamic profiles reduce drag, while the carbon construction and race geometry give the Madone Gen 8 a character suited to accelerations, climbs and fast group rides.
- Comfort at speed: The IsoFlow seat tube allows the saddle area to flex and absorb impacts from the road surface. This helps when you want to hold your position and keep pushing on uneven tarmac.
- Shimano 105 mechanical shifting: The Shimano 105 12-speed groupset combines 50/34 chainrings and a 11-34 cassette, offering a wide gear range for climbs and fast sections.
- OCLV 500 Series frame: The SL version uses OCLV 500 Series carbon and retains the Full System Foil profiles and IsoFlow of the Madone Gen 8 platform.
Aerodynamics, pedalling response and comfort work together: a Madone for the whole route, from the first climb to the fast ride home.
