Argon 18 will stop at nothing to reach new heights of excellence. The Nitrogen, a bike that has already proven itself on the international circuit—including at the iconic Tour de France—is getting the Pro treatment: it is now equipped with a stratospheric level of aerodynamic and lightweight integration. Offered with the exclusive carbon monocoque AHB5000 aero handlebar system, a lightweight and easy-to-use cockpit that generates up to a 30% increase in aerodynamics over standard round handlebars, and unparalleled adjust-ability, the Nitrogen Pro pushes the limits of performance and optimal balance.

Built to be the benchmark in ultimate aerodynamics. Reach new heights with Nitrogen Pro.

A Source of Inspiration for All Aero Bikes.
