Rider on the Argon 18 Dark Matter on a forest gravel trail

Built For The Unknown

The Dark Matter is made for gravel races, long days in the hills and everything in between.

Massive tyre clearance, smart storage and rugged geometry mean you can point it at almost any surface and keep going.

Responsive Gravel Geometry

The gravel geometry is drawn from Argon 18's endurance road platform, so the bike stays sharp and race-ready rather than sluggish.

The Topological Compliance System takes the edge off rough ground while keeping the frame stiff under power.

57mm Tyre Clearance

There is room for tyres up to 57mm wide, for extra grip and comfort on loose and broken surfaces.

The frame is also compatible with gravel suspension forks for the roughest routes.

Storage Built In

A hatch in the downtube opens into integrated storage for tools, spares and snacks.

Mounts for bags and mudguards, plus internal dynamo routing in the fork, make it ready for bikepacking too.
