Argon 18 Dark Matter GRX Gravel Bike
Where the pavement ends
Go way off the beaten path with this gravel racer featuring true road race-inspired geometry derived from Argon 18’s legendary race bikes. Some will blaze the trail, but on the Dark Matter, you will scorch it.
For when the route is unpredictable – but the ride must be solid. Head way off the beaten path with this gravel racer featuring performance-driven geometry derived from Argon 18’s legendary World Tour bikes. Go wherever the day takes you with assured handling and optimal power transfer, to control the terrain regardless of the surprises it may throw at you. We wanted a bike that offered supreme confidence alongside racing behaviour, a bike that would feel just as playful and responsive on the dirt as it would on the road.
Our gravel geometry provides fork rake specific to frame size, to allow for tight turn clearance on more technical runs, and with an eye toward ride quality, the Dark Matter features seatstays designed to flex and dissipate shocks. You'll also get three head tube extension heights for every frame size with our streamlined 3D+ system: 0mm, 15mm and 30mm.
Gravel racers looking for poppy performance and nimble responsiveness on all terrain.
