The all-new S-Works Tarmac SL9 Dura-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.
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.
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.
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.

Founded in California in 1974, Specialized began with a simple promise: serious riders deserve serious gear. Half a century later, the brand still funds its own wind tunnel, builds its own carbon, and tests every bike with the world's best so that you ride your own best.
The first production mountain bike. The first cycling-specific shoes. FACT carbon, the Win Tunnel, S-Works. Specialized has a habit of building the things the rest of cycling ends up copying.
