The Argon 18 Nitrogen 105 Di2 Road Bike is the fastest road bike ever produced by Argon 18, created as a complete system to deliver maximum speed, fit, and ride quality. Built for real-world conditions, it combines aerodynamic frame shaping, modern geometry, and a rider-focused fit with premium components to produce a high-performance machine that is fast, light, and responsive while retaining Argon 18’s renowned ride comfort.
The Nitrogen is developed with aerodynamics and rider efficiency at its core. Its geometry provides a race-ready position without compromising comfort for long days in the saddle. Every aspect of the frame has been optimised to balance control, speed and performance.
All Nitrogen models include specially designed bottle cages inspired by automotive airflow concepts, further improving aerodynamic efficiency and integration.
Argon 18’s ATTEN technology division leads innovation across the Nitrogen platform. Each ATTEN component is designed with a performance-driven purpose, addressing specific needs and pushing the boundaries of cycling technology.
The custom ATTEN CHB-01 Aero Handlebar enhances aerodynamics at the leading edge while optimising rider positioning. As part of Argon 18’s system-based approach, it ensures the frame and cockpit function together to minimise drag and maximise speed.
