Argon 18 Dark Matter Rival AXS Gravel Bike
The Argon 18 Dark Matter Rival AXS Gravel Bike is designed to take you off the beaten path, featuring new bikepacking options, cable integration, and refined stack and reach adjustments. Retaining its signature confident and responsive ride, this updated version continues to define gravel excellence.
3D System
The 3D System ensures an ideal fit without compromising safety, steerer stiffness, or design. By extending the headtube, it offers a wider range of positioning options to match the handlebar stack height preferences of every rider. With up to three head tube extension heights per frame size, it eliminates the stiffness loss typically caused by traditional spacers, maintaining precise handling in all positions. The streamlined design, complemented by custom 3D caps for each extension height, reflects meticulous attention to detail and refined aesthetics.
Gravel Geometry
Drawing from endurance geometry influenced by high-performance road racing designs, this approach prioritises handling, responsiveness, and race-ready positioning to meet the specific demands of gravel riders.
Argon Fit System
Designed to optimise performance and positioning across all sizes, the geometry is precisely adjusted for each frame size, ensuring a perfect fit for every rider.
