Product ID: 1176667

On gravel and mixed terrain, the Argon 18 Dark Matter Disc Gravel Road Frameset gives you control and assured handling.

The carbon frame and fork optimise power transfer, and the geometry is road racing-inspired, while there are aerodynamic touches too, including a truncated foil fork design, alongside the air-smoothing shape of the downtube and seat stays. Argon 18 have included their 3D+ system so there's height adjustment in the head tube that won't compromise rigidity. With space for 45mm wide tyres, there's plenty of capability to set the bike up to tackle the harshest terrain.

Argon 18 Dark Matter Disc Gravel Road Frameset 2020

Build up the Argon 18's Dark Matter Disc Gravel Road Frameset into a highly capable adventure racing bike. The geometry is derived from the brand's legendary WorldTour bikes so you get assured handling and efficient power transfer, and there's plenty of head tube height adjustment via the Horizontal Dual System (HDS), allowing you to dial in your position perfectly. The Dark Matter behaves like a race bike - lively and responsive - but is stable over loose terrain, and the carbon frame and fork are stiff yet compliant for speed and comfort. There's space for huge 45mm wide tyres to really smooth out rocks and rough terrain and is designed for disc-brakes, you'll get confidence-inspiring stopping power even when it's wet or muddy.
