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.

The Madone SLR 8 AXS Gen 8 is an ultra-aero, featherlight road bike that's built to race. Its 900 Series OCLV Carbon frame is not only aerodynamic, but also ultra-light for flying up climbs. Lightweight IsoFlow frame technology means that the Madone doesn’t sacrifice comfort for speed. To give you every aero advantage, the Madone SLR comes with RSL Aero Bottles and Cages that further reduce drag. This build comes ready to win with a SRAM RED AXS drivetrain with a power meter, carbon wheels and a Trek Aero RSL one-piece carbon bar/stem.
