just levelled up with the arrival of its fastest gravel race bike ever, the Anti Matter - delivering aero speed, stiffness, control, and efficiency in one complete system. Its is a beautiful bike that we are excited about!
Ok…now for the bike nerd engineering stuff to back up the marketing:
The Anti-Matter’s aero platform was refined through over 800 hours of CFD simulation, 45 hours of wind tunnel testing, and more than 130 tube profile iterations, delivering a measured 14.5W aerodynamic advantage over their Dark Matter in race conditions (+/–15° yaw, wind-averaged drag at 45 km/h). This process ensures that performance translates beyond theory. A key objective for Argon 18 throughout development was achieving road bike level efficiency on gravel terrain, without compromising stability, control, or stiffness when conditions become rough and unpredictable.
The Anti Matter platform features:
- ATTEN CHB-01 one piece cockpit, designed to optimize front-end aerodynamics and support a race-oriented riding position.
- It is also equipped with proprietary aero bottle cages and
- co-developed ATTEN x Apidura frame bags, designed to carry race essentials with no aerodynamic penalty.
- The Anti Matter carbon frame brings a race-focused geometry, offering responsive handling at high speed, paired with up to 55mm tire clearance to adapt to modern gravel racing demands.
- available in 3 colourways, 3 groupsets, and a total of 5 configurations.
Gravel bikes continue to evolve to cover the full spectrum of off-road, adventure based riding, touring and racing. Get in touch with us to talk all things gravel - we can help you decide if an aero focused gravel rig needs to be added to your quiver. We have access to the Anti Matter now and can bring in yours whenever you are ready to take your gravel experience to the next level!
