Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Nothing is faster than the Tarmac SL8.

Thanks to a combination of aerodynamics, lightweight, and ride quality previously thought impossible, the Tarmac SL8 stands out. After eight generations and over two decades of development, it is more than the fastest Tarmac ever - it's the world's fastest race bike. 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, the ride science team knows the Tarmac SL8 is the fastest race bike ever made on the routes that matter.

Features:

  • 16.6 seconds faster over 40km.
  • 128 seconds faster over Milan San Remo.
  • 20 seconds faster over the legendary Tourmalet climb.
