Argon 18 Nitrogen Pro Road Bike
About Argon 18 Nitrogen Pro Frameset
A bike that aims to cheat the wind, the Argon 18 Nitrogen Pro is an aero race weapon that has been ridden in the Tour de France.
The Nitrogen Pro is Argon 18's foray into the world of aero road frames. Designed as the primary weapon for the sprinters of the BORA-Argon 18 team, it's built for speed and retains principles of the brand’s Optimal Balance philosophy - equal emphasis on light weight, rigidity and comfort.
The shape of the Nitrogen’s Nanotech HM8003 tubes indicates its intended purpose - minimizing drag. It’s aimed at sprinters, breakaway artists, and anyone who spends time riding solo.
A massive development for Argon 18 is the AHB5000 aero handlebar, which is the company's proprietary cockpit setup that aims to provide an energy-saving advantage through better aerodynamics.
Made of carbon, the new AHB5000 aero handlebar provides a sleek new frontal surface for the Nitrogen frame, which offers the benefits of a one-piece system but with more adjustability. With a jaw clamp system within the built-in stem, a single M8 bolt adjusts the length of the stem thanks to a 20mm spacer (included with the frame). A dust cap covering the jaw clamp prevents contaminants compromising the integrity of the system.
There are also computer mount drillings under the front of the handlebars, to further integrate the cockpit and offer aerodynamic savings; the overall setup offers a drag saving of 30% compared to a standard, round bar and stem offering.
Included with each Nitrogen Pro frameset are two stem 'back-ends' and a 20mm spacer; this allows you to dial in the fit of your Nitrogen Pro.
With X-Small frameset: Small & Medium stem (70 & 80mm) + 20mm spacer + 40cm bars
With Small frameset: Small & Medium stem (70 & 80mm) + 20mm spacer + 42cm bars
With Medium frameset: Small & Medium stem (70 & 80mm) + 20mm spacer + 44cm bars
With Large frameset: Medium & Large stem (80 & 90mm) + 20mm spacer + 44cm bars
With X-Large frameset: Medium & Large stem (80 & 90mm) + 20mm spacer + 44cm bars
The Nitrogen boasts a modified version of Argon 18’s 3D head tube system; technology that allows you to structurally adjust the head tube height so that you can raise or lower the handlebar position without traditional headset spacers. According to Argon 18 test results, raising the bar 15mm with the 3D system results in 5 percent more rigidity compared to standard setups. And raising it 25mm saves you 11 percent more rigidity. The 3D adjuster pieces on the Nitrogen have a special aero shape that integrates with the frame, complementing the narrow profile of the head tube’s hourglass shape.
The Nitrogen’s monocoque carbon fork was designed using extensive CFD modeling to pair up with the frame and provide maximum aero advantage without sacrificing weight or rigidity. The front brake, co-developed by Argon 18 and TRP specifically for the Nitrogen, is tucked neatly behind the fork, away from the wind. The control cables route cleanly into the top tube, just behind the stem, to further enhance the clean look of the cockpit area. The trailing side of the downtube has a flattened profile, a design aimed at using standard round water bottles with minimal drag.
