The Tarmac SL8 Expert is unbeatable in speed. Its advanced aerodynamics and lightweight design provide a ride quality previously deemed 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 lightweight construction alone do not determine race outcomes – at the finish line, it all comes down to speed. Achieving race speed requires a specific balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science Team has found through race simulations based on real data that the Tarmac SL8 is the fastest road bike ever constructed on critical 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.
