Designed for riders who demand uncompromising performance on the road, the Argon 18 Nitrogen is a no-limits aero race bike built to go fast—everywhere, all the time. From flat-out sprints to long breakaways and rolling terrain, the Nitrogen delivers explosive speed with refined control.
At the core of the Nitrogen is Argon 18’s advanced aero carbon frame, engineered to slice through the wind while maintaining exceptional stiffness and ride quality. Every tube shape, junction, and integration detail is optimized for real-world aerodynamics, translating your power directly into forward momentum. Internal cable routing, race-tuned geometry, and clearance for modern road tires make the Nitrogen as clean and efficient as it is aggressive.

Whether you’re lining up for criteriums, chasing PRs on your favourite climbs, or building a high-performance road machine tailored to your goals, our team will ensure your Nitrogen is precisely fit and perfectly dialled. From cockpit setup to drivetrain optimization, every detail is tuned for maximum speed and confidence.
If your riding is defined by ambition and acceleration, the Argon 18 Nitrogen—expertly built and fit at HYPT Bike Performance—is ready to turn every watt into pure speed.
