SpecializedS-Works Tarmac SL9 Dura-Ace Di2 Road Bike
The all-new S-Works Tarmac SL9Dura-Ace Di2 Road Bike is officially the fastest road bike ever made—a purebred race machine engineered to turn your every effort into maximum velocity and dominate British roads. If your goal is to smash your personal bests on iconic climbs, conquer the local club run, or step onto the top step of the podium, this bike is your ultimate weapon. Featuring an ultra-lightweight FACT 12r carbon frame, cutting-edge aerodynamics, and a premium Shimano Dura-Ace Di2 drivetrain, the Tarmac SL9 leaves absolutely no room for compromise.
Unmatched Real-World Speed and Lowest Time to Finish
While other bike brands obsess over static wind tunnel data, the Tarmac SL9 is designed for the unpredictable, gritty conditions of real-world riding. It delivers the lowest real-world Time to Finish of any road bike in history. Whether you are battling blustery headwinds, navigating technical corners, or sprinting for the finish line, its performance has been validated across real race courses with real riders. It does not just feel faster—it objectively gets you across the line ahead of the competition.
Featherweight FACT 12r Carbon Frame
Weight-weenies and hill-climb specialists alike will marvel at the engineering of the S-Works Tarmac SL9. At the heart of the build is the revolutionary FACT 12r carbon frame, tipping the scales at an astonishingly svelte 687 grams. With the complete bike weighing in at a mere 6.6 kg, you get a machine that defies gravity on steep gradients without sacrificing the structural stiffness needed for explosive accelerations and precise, razor-sharp handling on technical descents.
Seamless Integration and Premium Components
Every single component on the Tarmac SL9 has been curated to cheat the wind and maximise your efficiency. The Roval Rapide Integrated cockpit completely cleans up the front end for unparalleled aerodynamic gains, while the ultra-fast Roval Rapide CLX III wheels slice through crosswinds with ease. Paired with the flawless, lightning-fast shifting of the flagship Shimano Dura-Ace Di2 electronic drivetrain, this bike offers a seamless connection between rider and road, ensuring every watt is converted into pure speed.
