Trek Madone SL 7 Gen 8 2025
Couldn't load pickup availability
Trek Madone SL 7 Gen 8 2025 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 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. This helps when you want to hold your position and keep pushing on uneven tarmac.
- Ultegra Di2: The Shimano Ultegra Di2 12-speed electronic shifting works with 50/34 chainrings and a 11-34 cassette: compact gearing for routes with elevation changes.
- Carbon wheels: The Bontrager Aeolus Pro 51 wheels are made from OCLV carbon and are Tubeless Ready, with Bontrager R3 tyres in 28mm for road riding.
Aerodynamics, pedalling response and comfort work together: a Madone for the whole route, from the first climb to the fast ride home.
