Argon 18Dark Matter Rival AXS XPLR E1 Gravel Bike
The Argon 18 Dark Matter is more than just a gravel bike. It is designed to tackle challenging terrain both physically and mentally. Built for riders who push forward when the trail becomes tough, it excels in conditions others avoid. When the road ends and the challenge begins, the Dark Matter is ready.
Tyre clearance (57 mm)
Generous tyre clearance allows the use of larger tyres for improved traction, comfort and versatility. Perfect for technical trails or long rides on unpredictable surfaces.
Integrated downtube storage
Discreet downtube storage offers space for essentials such as tools, snacks or a spare tube, keeping the bike clean and uncluttered.
Adventure-ready geometry
Engineered for control and stability across varied terrain. The relaxed geometry provides comfort on long rides over rough ground. Compatible with a front suspension fork for added control and comfort.
1x drivetrain
The 1x drivetrain delivers smooth, efficient shifting with fewer moving parts, reducing maintenance and increasing reliability on rough terrain. A hidden front derailleur mount is included for those who prefer a 2x setup.
Dropper post compatibility
Supports the addition of a dropper post to enhance control on technical descents by lowering the centre of gravity for better handling on steep, rocky trails.
Mounting points for bottles, racks and mudguards
Versatile mounting options allow for extra water, gear or weather protection, ideal for bikepacking or long day rides.
Dynamo routing in the fork
Integrated fork routing accommodates a dynamo system to keep lights and devices powered while maintaining a clean bike appearance.
Internal cable routing
Cables run internally for a tidy look and easy use with handlebar bags or other accessories.
