S-Works Tarmac SL8 frame, no bike is as fast as the Tarmac SL8 thanks to a combination of aerodynamics, light weight, and ride quality previously thought impossible. After eight generations and more than two decades of development, it's not just the fastest Tarmac ever-it's the fastest road bike in the world. Are your legs ready? Aerodynamics or lightness alone do not win races: what matters is speed. Achieving that speed requires creating an uncompromising combination of aerodynamics, lightness, stiffness, and stress absorption. Thanks to complex simulations using real data, our Ride Science Team has verified that the Tarmac SL8 is the fastest race bike on any course:- 16.6 seconds on 40 km of flat terrain, 128 seconds faster on the Milan-San Remo course, 20 seconds faster on the Tourmalet climb.
