Developed and engineered for optimal interaction between aerodynamic frame design, modern geometry, flexible rider fit & world-class components, the Nitrogen Pro is built to perform in real world conditions, offering the performance and ride quality Argon 18 is recognized for. The Nitrogen Pro delivers speed, lightness, fit and ride optimization.  

‘’Argon 18 is extremely proud to launch the new Nitrogen platform – the return of an iconic name, reimagined for the riders of today and tomorrow, and a clear signal of where Argon 18 is headed. Three years in the making, thousands of hours of hard work, this project represents a deep commitment to innovation, performance and pushing the boundaries of our development approach. This is more than a comeback; it’s a glimpse into the future of Argon 18.’’ - Alexandre Côté, Product Director 

With the goal of creating the world’s fastest road bike, Argon 18 engineers also built solutions from the ground-up to achieve unprecedented aerodynamics. Rather than designing a frame and pairing it with standard components, Nitrogen Pro was built as a fully integrated aerodynamic system, honed using a CFD model featuring the bike and rider matched with specific component combinations for optimal performance.  Argon 18 used this approach to ensure theoretical performances would be achieved in real world conditions – not just in a wind tunnel. 

“We realized that making the fastest bike on the market isn’t possible using status-quo design approaches and readily available components.  We engineered a complete ecosystem that includes the rider, the frame geometry, component design, collaborations, integration, and real-world performance.” – Vincent Lemay, Vice-President of Research & Development

A standout feature of the Nitrogen Pro is the ATTEN x Scope Artech 6.A+ wheelset, developed in collaboration with Scope Wheels. This wheelset, born from Scope’s world-renowned Artech 6.A model, is a fully integrated component of Nitrogen Pro’s front-end aero system.  Enhancements to the Artech 6.A were made, for maximum performance and speed across tarmac, pavé, chip seal, and beyond, thanks to a form specifically tailored for Nitrogen Pro, when ridden with a 700x30c tire.  The result is an exceptionally smooth ride, at top speeds and over all road surfaces.  No compromises. 

The Nitrogen platform also features a custom ATTEN CHB-01 Aero Handlebar that simultaneously optimizes leading edge aerodynamics and rider positioning. All Nitrogen bikes are delivered with specially designed bottle cages that incorporate an airflow concept inspired by automotive design.   

The Nitrogen platform is available with two carbon fibre layup options, 3 colourways and a total of 6 different builds. Bookings and pre-orders are open, and delivery to Argon 18 dealers will start in November 2025.  Customers can purchase the bike through their local dealer, which can be found through the dealer locator on Argon18.com.
