The Trek Madone SLR 9 Gen 8 is the pinnacle of Trek’s road racing innovation. Developed for riders who demand nothing less than excellence, this is the fastest, most refined Madone to date. At its core is an ultra-lightweight 900 Series OCLV Carbon frame, shaped using Full System Foil aero tubing that optimises airflow around the entire bike; frame, cockpit, bottles and rider position.
IsoFlow technology sets the Madone apart from the competition, allowing the seat tube to flex subtly for improved compliance and less fatigue without compromising aerodynamic efficiency or frame stiffness. It’s a clever solution that lets you stay fresh over long, demanding rides.
The Shimano Dura-Ace Di2 R9200 groupset delivers flawless wireless electronic shifting across 24 gears. With programmable shifter buttons and incredibly quick response times, you can shift under load with absolute confidence. A Shimano Dura-Ace 52/36 chainset and 11-30T cassette give you the range to fly up climbs and keep the power down on the flats.
Bontrager Aeolus RSL 51 carbon wheels are built for speed, combining light weight with aerodynamic shaping and tubeless-ready compatibility. Wrapped in 700x28mm Bontrager RSL RD tyres with supple 170 tpi construction, the setup ensures speed with a surprisingly smooth ride feel. The Trek Aero RSL integrated cockpit adds to the sleek silhouette, while also being functional with Blendr mounts for lights or accessories.
For even more free speed, the RSL Aero Bottles and Cages seamlessly integrate into the frame design to reduce drag and keep hydration within reach. Every element of the Madone SLR 9 Gen 8 has been chosen for its ability to maximise performance, making it a bike that doesn’t just compete but leads the charge.
Whether you're aiming for podiums or simply want to ride the very best, the Madone SLR 9 Gen 8 is built to go faster, climb stronger, and ride longer with pro-level efficiency.
