This bike is something else. It’s so quick but yet feels really well balanced and gives you confidence at every point. Also massive thank you to Milo and the team who pulled out all of the stops to make sure everything was sorted.

Argon 18 Anti Matter Force XPLR AXS E1 Gravel Bike
The Argon 18 Anti Matter Force XPLR AXS isn't just a gravel bike; it is a meticulously engineered aerodynamic system designed for the uncompromising racer. Merging road-bike efficiency with rugged off-road capability, this platform is built to turn every watt into pure velocity. Featuring the revolutionary ATTEN CHB-01 aero cockpit, Zipp 303 XPLR S wheels, and a premium SRAM Force AXS groupset, the Anti Matter is the fastest, most integrated gravel machine Argon 18 has ever produced.
Aerodynamic Integration Without Compromise
While many gravel bikes simply add knobbly tyres to an endurance frame, the Anti Matter was developed as a cohesive aerodynamic unit. Every element, from the CFD-optimized tube profiles to the wide, deep fork design, has been refined to slice through the air at race pace. The ATTEN CHB-01 one-piece carbon cockpit provides a precise, aggressive riding position, while the proprietary side-load aero bottle cages and ATTEN x Apidura frame bag ensure your essentials don't create drag. This is a bike that respects the physics of speed, ensuring you stay fresher for longer when battling the wind on exposed gravel sectors.
Elite Componentry and Power Transfer
The heart of this build is the SRAM Force XPLR AXS E1 wireless groupset, offering lightning-fast shifts and a wide-range 10-46T cassette to conquer any gradient. Power is nothing without efficiency, which is why the Anti Matter features an oversized T47 bottom bracket and CeramicSpeed SLT bearings, providing a stiff, frictionless foundation for the SRAM Force XPLR Power aero crankset. Whether you are sprinting for a finish line or climbing a steep fire road, the pro-level carbon layup ensures that every ounce of effort is transferred directly to the dirt.
Unrivalled Control on Technical Terrain
Speed is worthless if you can’t control it. The Anti Matter provides incredible stability via the Zipp 303 XPLR S wheelset paired with Schwalbe G-One RS PRO 45c tyres, offering the perfect balance of rolling resistance and grip. Despite its aero-first geometry, the frame boasts a massive 55mm tyre clearance, giving you the versatility to tackle the muddiest or most technical courses with confidence. The horizontal, dropped seatstays work in tandem with the Argon 18 TDS-C Nitrogen Pro seatpost to dampen high-frequency vibrations, reducing fatigue and allowing you to maintain a precise line when the conditions get rough.
Race-Ready Reliability and Maintenance
Argon 18 has paired high-performance tech with practical solutions for the modern racer. The inclusion of the Universal Derailleur Hanger (UDH) makes sourcing spares simple, while the CeramicSpeed T47 DUB BB ensures longevity and ease of service in even the harshest environments. From the Ciclovation Grind Touch bar tape for superior grip in the rain to the weight-saving Repente Quasar 2.0 saddle, every component has been chosen to withstand the rigours of elite competition. This is more than a bike; it is a relentless, race-winning system.
