The S-Works Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight design provide a riding experience that once seemed unattainable. After eight generations and over twenty years of development, it is not only the fastest Tarmac ever created – it is the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not win races – at the finish line, it's all about speed. Achieving race speed requires a specific balance of aerodynamics, lightweight construction, stiffness, and compliance. Our Ride Science team has discovered through racing simulations based on real data that the Tarmac SL8 is the fastest road bike ever built on critical courses. It is a remarkable 16.6 seconds faster over 40 km, 128 seconds quicker in the Milano–Sanremo, and 20 seconds faster on the Tourmalet.
