The Tarmac SL8 is unbeatable in speed. With its advanced aerodynamics and lightweight construction, it offers a riding 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 it is also the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not decide races—what matters at the finish line is speed. To achieve race speed, a specific balance of aerodynamics, weight, stiffness, and compliance is required. Our Ride Science Team has utilized racing simulations based on real data to determine that the Tarmac SL8 is the fastest road bike ever built on crucial routes. It is 16.6 seconds faster over 40 km, 128 seconds quicker at Milan–Sanremo, and 20 seconds faster on the Tourmalet.
