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 - it is also the fastest road bike in the world. Are you ready? Aerodynamics and light weight alone do not determine race outcomes - it is all about speed at the finish line. Achieving race-speed requires a precise balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science team has determined through race simulations based on real data that the Tarmac SL8 is the fastest road bike ever made on critical routes. It is a full 16.6 seconds faster over 40 km, 128 seconds quicker in the Milano–Sanremo, and 20 seconds faster on the Tourmalet.
