From rough race days to the unknown, the Dark Matter is your ultimate gravel machine. With massive tire clearance, smart storage, and rugged geometry, it powers through any terrain. 

Whatever the ride throws at you—get over it.
Gravel throws unique challenges at riders, therefore it demands unique frame characteristics.  gravel geometry draws on Argons endurance geometry, which derives directly from Argons performance road race series, meaning handling, responsiveness and race-ready positioning are paramount. Gravel and endurance both call for a longer wheelbase than a performance road bike, which you'll see on both the Krypton and Dark Matter. The Dark Matter features a higher bottom bracket and adjusted headtube angle and raked fork to adjust our hallmark precision handling to a wider tire size windows (up to 45C); both for ride quality and to avoid toe overlap on the twists and turns of more technical rides. Gravel geometry also features a slightly more upright position, providing a higher degree of comfort on rougher surfaces and long-haul routes.
ize-specific geometries to provide optimal performance and positioning for all riders
Argon 18's fit system offers size-specific geometries to provide optimal performance and positioning for all sizes, guaranteeing no rider left behind.

Our smallest bike frames offer the same ride feel as our largest frames. In fact, our XL frames have exceptional stiffness without excess weight, to avoid the 'dead' feel found in some larger frames. XS and XXS retain their inherent lightweight qualities, but without excess stiffness, avoiding harsh ride quality.
