Argon 18:

Hit the dirt. Hit it fast.

Go way off the beaten path with this gravel racer featuring a true road race-inspired geometry derived from Argon 18’s legendary race bikes. It may be more stable, it may sport big tires, yet the Dark Matter is so responsive that it will change the gravel bike game forever. Some will blaze the trail; on the Dark Matter, you will torch it


When we set out to design the Dark Matter, we made sure not to come up with just another gravel bike. Our vision was to build a true gravel racer: a fast dirt road bike with a geometry adapted from our celebrated road frames. We wanted a bike offering improved stability but with a racing behavior, a bike that would feel just as fast and responsive on the trail that it would on the road. Mission accomplished.


The Dark Matter has a longer wheelbase than our endurance bikes, but it remains shorter than most other gravel bikes available with equivalent tire clearance. This is only possible with our dropped chain stay design. The Dark Matter offers a longer front end than our road bikes. It adds stability and prevents toe overlap. True to our design ethos and road race background, the Dark Matter was primarily intended to be used with 700c wheels although 650c wheels will work depending on tire width.
