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.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

ARGON18 Sum Pro Ultegra Di2 Black

Season:2024

Brand:Argon 18

Code:A18BK24SMPUi2BK

All Together Faster
Decisions, decisions… made easy. With a bike that gives you flat-out advantage on the climbs, the sprints and the straightaways, the only decision you’ll need to make is how nice you want to be to the other guys.

A rider-oriented design approach ensures a frame that is both rooted and responsive, with a ride experience most aero frames can’t match. With a layup engineered to maximise aerodynamics while keeping weight low, the design process for the Sum allowed us to strip away all unnecessary weight within the new aero profile tube shapes - all while maintaining maximum power transfer.

Own the season: the Argon18 Sum Pro will get you ahead on the climbs, keep you there on the flats, and power you through the sprints.

3D System
Get the best fit window without compromising the safety, steerer stiffness, or looks of your bike with Argon 18's 3D Technology.

Road Race Geometry
Argon18's road race geometry is designed around the razor-sharp reflexes and precision handling required for racers of all levels.

Argon Fit System
Argon Fit System is designed to provide riders of all sizes with consistent performance and optimal positioning.
