The 2020 Argon 18 Dark Matter GRX takes you ever further off the beaten path with new bikepacking features, cable integration, and updated stack and reach. What hasn’t changed is the confident, responsive ride that’s made it a gravel classic. Light and lean and ready to race, or now with up to four bottle mounts and full paniers, the Dark Matter goes from scrappy race-day ride to sidekick for your longest off-road adventures.
