Nothing is faster than the Tarmac SL8 thanks to a combination of aerodynamics, lightweight, and ride quality previously thought impossible. After eight generations and over two decades of development, it's more than the fastest Tarmac ever — it's the world's fastest race bike. 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, 20 seconds faster over the Tourmalet.
