TrekMadone SLR 9 Project 1 Dura Ace Di2 Road Bike
The Trek Madone SLR 9 Gen 8 Road Bike is engineered to rule the road, seamlessly combining ultra-lightweight construction with cutting-edge aerodynamics. Built from Trek’s elite 900 Series OCLV Carbon, the frame delivers exceptional stiffness at an incredibly low weight, while advanced aerodynamic tube shaping maximises efficiency on descents and fast, flat sections. IsoFlow frame technology enhances ride comfort without sacrificing speed, keeping you fresher deeper into the race.
This proven race machine is outfitted with Shimano’s flagship Dura-Ace Di2 electronic drivetrain, delivering lightning-fast, fully customizable shifting. Bontrager Aeolus RSL 51 tubeless carbon wheels provide exceptional speed and stability, complemented by the Trek Aero RSL one-piece carbon bar/stem for a clean, aerodynamic cockpit. Integrated RSL Aero Bottles and Cages further reduce drag for every marginal gain.
Designed for serious racers who demand the very best, the Madone SLR 9 Gen 8 delivers uncompromising aerodynamics, comfort, and lightweight performance—true superbike capability for any road, in any condition.
