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.

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

GO ON.
GET LOST.

Really – go get lost. You’ve got extra snacks, gear, and you’ve got the bike that will go anywhere with you. Kicking up rocks on an old logging road? No problem. Muddy singletrack? Comes off easy. Grit pinging your frame for the next hundred miles? Didn’t notice.

Get even further off the beaten path with a bikepacking-ready ride with fender and rack mounts, and up to six bottle and utility mounts, depending on size. Also with internal cable routing at the headset and external at chainstays, and our 3D headset with cable integration for easy maintenance and dialed-in fit options.

Get rough and ready for anything with the Grey Matter. The gravel-specific handling and features that made the Dark Matter the ultimate gravel machine is now available in an alloy frame.

3D System

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

Gravel Geometry

Our gravel geometry draws on our endurance geometry, itself directly inspired by our performance road race series, meaning handling, responsiveness and race-ready positioning are paramount.

Topological Compliance System

Proprietary design method to offer exceptional vertical compliance and dampened road-induced vibrations while retaining maximum stiffness.
Each bike model featuring TCS technology was individually analysed to optimize frame topology and carbon layup.

Argon Fit System

Argon 18's fit system offers size-specific geometries to provide optimal performance and positioning for all sizes, guaranteeing no rider left behind.
