The Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight design provide an unparalleled riding experience that once seemed unattainable. After eight generations and over twenty years of development, it is not only the fastest Tarmac ever made – it is the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not determine race outcomes – at the finish line, speed is what matters. Achieving race-speed requires a specific balance of aerodynamics, lightweight construction, stiffness, and compliance. Our Ride Science Team has determined through racing simulations based on real data that the Tarmac SL8 is the fastest road bike ever built on critical segments. It is 16.6 seconds faster over 40 km, 128 seconds faster at Milan-Sanremo, and 20 seconds faster on the Tourmalet.
