The S-Works Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight design create 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 but also the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not win races – speed is what counts at the finish line. Achieving race speed requires a specific balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science Team, through racing simulations based on real data, has determined that the Tarmac SL8 is the fastest road bike ever built on key courses. It is a remarkable 16.6 seconds faster over 40 km, 128 seconds faster at Milano–Sanremo, and 20 seconds faster on the Tourmalet.
