Featuring a Pro-level carbon layup and the proprietary ATTEN integrated cockpit, the Nitrogen Pro is built for the podium, offering a sub-7kg profile that defies the traditional limits of an aero road bike.

Argon 18 Nitrogen Pro: A Samurai Sword for the Road
The Nitrogen Pro represents the pinnacle of Argon 18 engineering. Inspired by the track-proven Electron Pro TKO, it utilises horizontal dropped seat stays and a flow-optimised headtube to reduce drag in real-world conditions. This isn’t a bike designed solely for a wind tunnel; it is designed for the sharp reflexes and precision handling required in the heat of a breakaway. With its ultra-stiff oversized bottom bracket and integrated aero bottle system, the Nitrogen Pro ensures that every watt is converted into pure, relentless velocity.
