Argon 18 Introduces the All New 2025 Dark Matter: Get Over it.
All day adventure – no matter what, no matter where.
We know adventure gravel throws a lot at you: ruts and rocks, washboard and washouts, remote single track and dusty country roads. No matter what the adventure has in store, with 57mm tire clearance, integrated storage, and adventure-specific geometry, the all new 2025 Dark Matter lets you get over it.




Engineered for grit and designed for riders who want to get over any challenge, the Dark Matter is a high-performance gravel bike made to take on the tough stuff. With massive tire clearance, it powers through loose gravel, chunky rock, and deep ruts without flinching. Adventure-specific geometry balances long-distance comfort with razor-sharp control, providing the confidence to stay fast and composed even when the road disappears. The 2025 Dark Matter achieves those specific handling characteristics with a longer wheelbase and longer chainstays than the previous version, and also a slightly longer reach (between 5-15mm, size dependent) and higher stack (10mm). The head tube angle is also one degree slacker than earlier versions.
The new Dark Matter lets you stay sleek, light, and self-reliant, no matter how far you go. With integrated downtube storage and multiple mounting points for bottles, racks, and fenders, the Dark Matter can go fully loaded for the long haul—or stripped back for maximum speed. With a 100-150 gram weight savings over the previous version, that speed will come easy. Optimized for a 1x drivetrain, the Dark Matter delivers smooth, efficient shifting with fewer moving parts—meaning less maintenance and more reliability on rough terrain. Add a 2x drivetrain, suspension fork, or dropper post, and the Dark Matter adapts to the way gravel riders want to ride.
This isn’t just another gravel bike – it’s the voice in your head telling you to keep going, the riding partner whose sense of adventure always inspired you. Got a challenge for this season? Get ready to get over it.
