Dark Matter GRX Gravel Bike

Argon 18 Dark Matter GRX Gravel Bike

The Argon 18 Dark Matter GRX Gravel Bike is more than just a gravel bike. It is engineered to take on tough terrain, both physically and mentally. Made for riders who push through when the going gets difficult, it excels where others turn back. When the road ends and the challenge begins, the Dark Matter is ready.

Tyre clearance (57 mm)
Ample tyre clearance allows for larger tyres that improve traction, comfort and versatility. Well suited to technical trails and long days on variable surfaces.

Integrated downtube storage
Built-in downtube storage provides space for ride essentials such as tools, snacks or a spare tube, helping to keep the bike organised and streamlined.

Adventure-ready geometry
Geometry designed for control and stability over unpredictable terrain. The relaxed fit offers lasting comfort on extended rides. Compatible with a front suspension fork to boost control and comfort on rougher ground.

1x drivetrain
Fitted with a 1x drivetrain for smooth, efficient shifting and minimal maintenance. Fewer moving parts enhance reliability over rough terrain. A concealed front derailleur mount is included for those who may prefer a 2x system.

Dropper post compatibility
Allows for the addition of a dropper post, offering improved control on steep or technical descents by lowering the centre of gravity.

Mounting points for bottles, racks and mudguards
Multiple mounting points provide room for water bottles, luggage or weather protection. Ideal for bikepacking and long-distance adventures.

Dynamo routing in the fork
Internal fork routing supports a dynamo setup, enabling riders to power lights and devices without cluttering the bike’s clean look.

Internal cable routing
Cables run internally for a neat appearance and easier use with handlebar bags or other front-mounted accessories.
