The Dark Matter in action

Technology Dark Matter

3D System

Get the best fit window without compromising the safety, steerer stiffness, or looks of your bike with Argon 18's 3D Technology.

Gravel Geometry

Our gravel geometry draws on our endurance geometry, itself directly inspired by our performance road race series, meaning handling, responsiveness and race-ready positioning are paramount.

Topological Compliance System

To achieve the optimal balance of comfort and performance for our endurance line, we needed geometry uniquely aligned with the demands of long-distance riding and racing. In conjunction with the best geometry, we also needed to optimise frame topology and carbon layup.

Argon Fit System

Argon 18's fit system offers size-specific geometries to provide optimal performance and positioning for all sizes, guaranteeing no rider left behind.
