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.

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.

The Grey Matter in action

Technology Grey Matter

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.

What the
media say

The Grey Matter is a sharp bike. It’s simply ready to go, ready to tackle whatever route you want to take on.

"A very responsive bike with solid handling. Even when it gets steep and you have to go around a sharp curve on gravel, there is grip at the same time as you have a feeling of being in balance and in control of the bike."
