The Argon 18 Nitrogen brings race-proven aero weaponary to your weekend rides.
The Nitrogen brings Argon 18's aero road frame to a greater number of riders thanks to its unbeatable performance-to-price ratio. While the sprinters of the BORA-Argon 18 team may use the Nitrogen Pro, get all the aero performance and benefits of Argon 18’s Optimal Balance philosophy - with its equal emphasis on light weight, rigidity and comfort - in the Nitrogen.
The shape of the Nitrogen’s Nanotech HM6003 tubes indicates its intended purpose - minimizing drag. It’s aimed at sprinters, breakaway artists, and anyone who spends time riding solo.
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.

The Nitrogen also features Argon 18’s Horizontal Dual System, which balances stiffness and compliance for a comfortable ride. Imagine a diagonal line running from the head tube down to the rear dropouts. Everything below the line represents the 'Power Zone', where rigidity matters most. In the case of the Nitrogen, that means a stiff, aero-shaped head tube up front to ensure crisp, precise handling while cornering or sprinting, combined with a massive bottom bracket area and asymmetrical chainstays to maximize every bit of energy you put into the pedals. The threadless BB86 bottom bracket further boosts stiffness with no added weight.
The 'Comfort Zone' consists of smaller, thinner frame tubing up top to add compliance and give it a smoother ride.
The aero-shaped carbon seatpost is reversible, offering 72 or 76.5-degree effective seat angle options. And the clamp is movable, allowing you to dial back the seat angle to 78 degrees — perfect for quickly dialing in your position for triathlon or TT riding. Inside the post is an integrated mount for a hidden Di2 electronic drivetrain battery.
Argon Fit System (AFS) road geometry ensures that in every frame size, the dimensions remain proportional and well balanced, offering riders of various physical types equal ease in finding the optimal position. Furthermore, handling and stability are enhanced by proper weight distribution and frame/fork geometry, ensuring the optimal balance between quick, nimble steering and the necessary stability in fast descents and on rough roads. Regardless of size, the Nitrogen Pro performs consistently, offering an efficient, comfortable position, agile, sure-footed handling, in all frame sizes.
Add to this a bottom bracket set 75 mm below the wheel axles - this lower bottom bracket lowers the cyclist's center of gravity and reduces head tube length, thereby improving rider control while increasing the frame's lateral rigidity. The end result is more accurate trajectories in turns, and more stability at speed.

More About The Manufacturer Argon 18
Argon 18 is a Canadian cycle manufacturer founded in 1989 by Gervais Rioux in Montreal, Quebec. The name is derived from the element, which is number 18 on the periodic table of elements; it's also one of six natural noble gases. After retiring as a rider, ex-Olympian Rioux opened a bike shop, where the brand was born. In 2001 they produced their first carbon frame and the brand is now distributed in 31 countries. Argon 18 sponsors German pro cycling team Bora-Argon 18 and debuted at the Tour de France in 2015.
