The Tarmac SL8 Expert is incredibly fast. The advanced aerodynamics and low weight deliver a riding quality that seemed unattainable. After eight generations and more than twenty years of development, it is not only the fastest Tarmac ever made—it is the fastest racing bike in the world. Are you ready? Aerodynamics and low weight alone don't win races—what matters is speed at the finish line. Achieving race speed requires a precise balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science team discovered through race simulations using real data that the Tarmac SL8 is the fastest racing bike ever built on the critical tracks. It is 16.6 seconds faster over 40 km, 128 seconds faster at Milano–Sanremo, and 20 seconds faster on the Tourmalet.
