Trek Madone SLR 7 8th Gen road bike Shimano Ultegra Di2 12-speed Bontrager Aeolus Pro 51 Serpentine 2027

The Trek Madone SLR 7 8th Gen Shimano Ultegra Di2 12v Bontrager Aeolus Pro 51 Serpentine 2027 is designed for cyclists seeking an exceptional road bike that combines aerodynamics, lightness and efficiency to deliver top performance. Its 900 Series OCLV carbon frame, the most advanced in the range Trek, stands out for its remarkable stiffness and low weight. Combined with IsoFlow technology, it effectively enhances comfort by filtering out vibrations whilst maintaining maximum power transfer. The result is a responsive, precise and extremely high-performance bike, equally at home on attacks as it is on long, fast rides.

Developed with a firmly competition-focused approach, the 8th-generation Madone SLR features Full System Foil aerodynamic profiles, full cable integration and a one-piece Trek Aero RSL cockpit that optimises both aerodynamic efficiency and stiffness in the riding position. Its T47 bottom bracket promotes particularly efficient power transfer, whilst the clearance for tyres up to 32 mm provides greater comfort, grip and versatility. The full-carbon fork completes the package, offering precise handling and excellent stability, even at very high speeds.

This model is fitted with the Shimano Ultegra Di2 12-speed electronic drivetrain, renowned for the speed, smoothness and precision of its gear changes in all situations. The Bontrager Aeolus Pro 51 carbon wheels enhance the bike’s dynamic qualities thanks to their excellent balance of aerodynamics, stiffness and control, making it easy to maintain high speeds whilst remaining highly responsive during acceleration. With its integrated Trek Aero RSL cockpit, its Bontrager Aeolus Pro saddle with carbon rails and its premium components, the Madone SLR 7 Serpentine is a top-of-the-range racing machine designed for cyclists who refuse to compromise on performance.
