The Argon 18 Nitrogen Force AXS Bike is built around a single, demanding premise: that an aero road bike shouldn't ask you to compromise. Not on speed, not on weight, not on fit, and not on ride quality. Argon 18 designed the Nitrogen platform to deliver all four, packaging a thoroughly engineered carbon frame with a full SRAM Force AXS electronic groupset and the brand's own Atten CHB-01 aero cockpit into a complete machine that's ready to race at $8,599.
Show full description and specs
The Nitrogen's carbon frame is built with what Argon 18 calls Elite Level Layup — the same quality of construction and carbon processing applied to their Pro-level machines. Every aerodynamic detail has purpose: the Flow-Optimized Headtube uses extended volume and an angled edge to reduce drag at the front of the bike; the fork is wider, deeper, and faster than its predecessor; and the horizontal, dropped seat stays — a design cue borrowed from Argon 18's Electron Pro TKO track bike and E119 triathlon platform — keep the rear end stiff and efficient. Fully integrated cable routing and an oversized T47 bottom bracket shell round out a frame built for speed without making service unnecessarily difficult.
Mounted to that frame is the Atten CHB-01 Aero Handlebar, developed by Argon 18's own components brand. It's designed to be the aero front end the Nitrogen's frame deserves — shaped for drag reduction and real-world ergonomic control, with an integrated computer mount and size-specific widths calibrated to each frame size. Argon 18's Fit System means the Nitrogen isn't one-geometry-fits-all: each of the six sizes carries its own stack, reach, and cockpit dimensions, so the smallest rider and the tallest get a position actually designed for them.
Design Benefits
- Elite-level carbon construction without the Pro price — Argon 18's Elite Level Layup means the Nitrogen frame receives the same construction quality as the brand's Pro-tier bikes. The aero tube profiles, Flow-Optimized Headtube, and dropped seat stays…
