Specialized Tarmac SL8 Expert, no bicycle 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 a no-compromise combination of aerodynamics, lightness, stiffness, and shock absorption. Thanks to complex simulations using real data, the Specialized Ride Science Team has verified 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 Milano-Sanremo route, 20 seconds faster on the Tourmalet climb.
