Argon 18 Grey Matter Apex XPLR Gravel Bike
Prepare for any adventure with the Grey Matter Gravel Bike. This alloy-framed gravel bike inherits the gravel-specific handling and features that made the Dark Matter a standout in its class.
3D System: This innovative system ensures a perfect fit without compromising safety, steerer stiffness, or aesthetics. By extending the headtube, it offers a broader range of positioning options to suit every rider’s handlebar stack height preferences. With up to three head tube extension heights per frame size, the 3D System avoids the stiffness loss typically associated with traditional spacers, maintaining precise handling in all positions. A sleek design, complete with custom 3D caps for each extension height, showcases meticulous attention to detail and refined styling.
Gravel Geometry: Inspired by endurance geometry and high-performance road racing designs, this approach prioritises handling, responsiveness, and race-ready positioning, making it ideal for the unique demands of gravel riding.
Argon Fit System: Designed to enhance performance and positioning across all sizes, the geometry is precisely tailored for each frame size, guaranteeing a perfect fit for every rider.
