Description
The Argon 18 Dark Matter Force AXS XPLR 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 delivers an ideal fit window without compromising safety, steerer stiffness, or design. This integrated technology extends the headtube, providing a wider range of positioning options to accommodate the handlebar stack height preferences of every rider. Offering up to three head tube extension heights for each frame size, the system eliminates the stiffness loss associated with traditional spacers, ensuring precise handling in all positions. Its streamlined design, featuring custom 3D caps for each extension height, highlights exceptional attention to detail and refined aesthetics.
Gravel Geometry
Building on endurance geometry inspired by high-performance road racing designs, this approach ensures handling, responsiveness, and race-ready positioning are prioritised to meet the demands of gravel riders.
Argon Fit System
Tailored to deliver optimal performance and positioning across all sizes, the geometry is adjusted to suit each frame size, ensuring a perfect fit for every rider.
