Argon 18 Nitrogen

The Argon 18 Nitrogen is a road bike that sits proudly in the brand's lineup as a high-performance aero machine. First unveiled in 2015, it was designed to meet the demands of competitive cyclists and triathletes who crave speed and efficiency on the tarmac. This model is positioned as a versatile road bike, capable of impressive aerodynamics without sacrificing comfort for longer rides. With its sleek lines and aggressive geometry, the Nitrogen is intended to cut through the wind and deliver a swift ride.

Riding the Argon 18 Nitrogen on UK roads, you’ll immediately notice its aerodynamic prowess. The bike features a carbon frame, which not only contributes to its lightweight nature but also enhances stiffness, offering a responsive and direct feel. When you’re pushing hard on open roads or tackling rolling hills, the Nitrogen maintains momentum with ease. Its geometry strikes a balance between aggressive racing posture and all-day riding comfort, making it suitable for both quick sprints and longer sportives.

In comparison to its rivals, the Nitrogen stands out with its unique blend of aerodynamics and ride quality. Competing against models like the Specialized Venge or the Trek Madone, the Nitrogen might not always match their latest technological bells and whistles, but it offers a solid performance at a more accessible price point. It's particularly appealing for riders who appreciate a refined and straightforward aero road bike without unnecessary complications.

On the used market, the Argon 18 Nitrogen holds its value well, especially models from recent years that feature updated components. The 2020 and later models are particularly sought after for their integration of disc brakes, which enhance braking performance in wet UK conditions. Buyers will find that models equipped with mid-range groupsets like Shimano Ultegra offer the best balance of performance and value. However, it’s worth noting that earlier models with rim brakes might be available at a bargain.

Prospective buyers should be aware of a few common issues. While the Nitrogen is generally solid, ensure that the frame has been well-maintained to avoid any structural concerns. Pay close attention to the condition of the aero handlebars and wheelset, as these parts can be costly to replace. It's also wise to check for any signs of wear on the bottom bracket and headset, given their importance in maintaining ride quality.

What it's like to ride

The Argon 18 Nitrogen rides with a focus on speed and aerodynamics. On UK roads, its carbon frame provides a firm yet comfortable ride, absorbing road buzz while maintaining stiffness for efficient power transfer. The bike feels lively on sprints and steady during long rides, making it versatile for various road conditions. Its aero design aids in maintaining high speeds, especially beneficial in windy situations common in the UK.

Who it's for

The Argon 18 Nitrogen is ideal for road cyclists who prioritise speed and aerodynamics. It's suitable for those who participate in competitive cycling or triathlons, as well as enthusiasts looking for a swift, performance-oriented road bike.

Models from 2020 onwards are particularly desirable due to the addition of disc brakes. However, earlier models can offer good value if well maintained. The 2018-2019 versions with updated geometries also provide a good balance of performance and comfort.
