The Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight construction deliver a ride quality that once seemed unattainable. After eight generations and over twenty years of development, it is not just 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 – speed at the finish line is what matters. Achieving race speed requires a specific balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science Team has discovered through racing simulations using real data that the Tarmac SL8 is the fastest road bike ever built on critical courses. It is a full 16.6 seconds faster over 40 km, 128 seconds quicker at Milan-Sanremo, and 20 seconds faster on the Tourmalet.
