The S-Works Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics combined with a lightweight design create a ride quality that once seemed unattainable. After eight generations and more than twenty years of development, it is not only the fastest Tarmac ever made but also the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not determine race outcomes – at the finish line, what matters is speed. Achieving racing speed requires a specific balance of aerodynamics, lightness, 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 16.6 seconds faster over 40 km, 128 seconds quicker in the Milano–Sanremo, and 20 seconds faster on the Tourmalet.
