S-Works Tarmac SL8 - Shimano Dura-Ace Di2

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. Your legs up for it?

Aerodynamics or lightweight alone don’t win races - speed is what matters. Delivering that speed requires creating an uncompromising combination of aerodynamics, lightweight, stiffness, and compliance. Through race simulations using real world data our Ride Science team knows the Tarmac SL8 is the fastest race bike ever made on the routes that matter - 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, 20 seconds faster over the legendary Tourmalet climb.

SL8

Great bike! Just ride it and you be the Judge.

Perfect.

After having a Venge, then SL6, then Aethos; the Tarmac SL8 is exactly what I wanted. Venge speed with Aethos weight and comfort. Absolutely love it. Boris at Sheepshead Bay is just the best when it comes to getting top-end gear and taking care of all the little details.
