S-Works Tarmac SL8 Frame, no bike is as fast as the Tarmac SL8 thanks to a combination of aerodynamics, lightness, and ride quality previously thought impossible. After eight generations and over two decades of development, it is not only the fastest Tarmac ever: it is the fastest racing bike in the world. Are your legs ready? Aerodynamics or lightness alone do not win races: what matters is speed. To achieve this speed, it is necessary to create an uncompromising combination of aerodynamics, lightness, stiffness, and shock absorption. Thanks to complex simulations using real data, our Ride Science Team has confirmed that the Tarmac SL8 is the fastest racing bike on any course: - 16.6 seconds faster over 40 km of flat, 128 seconds faster on the Milan-Sanremo course, 20 seconds faster on the Tourmalet climb.
