All Together Faster
Meet the best of the best: aero to match the Nitrogen, pure road performance to match the Gallium Pro, with race-ready handling and premium ride quality. The all-new Sum Pro features our most advanced layup and technologies to get you to the front of the group and keep you there, through the climbs, the corners, and the sprints.

Quiver-killer? You want more than that. From the climbs to the crits, you’ll accept no compromises in aero performance, lightweight advantage, and flat-out, bunch sprint handling.

3D System
Get the best fit window without compromising the safety, steerer stiffness, or looks of your bike with Argon 18's 3D Technology.

Road Race Geometry
Our road race geometry is designed around the razor-sharp reflexes and precision handling required for racers of all levels.

Topological Compliance System
To achieve the optimal balance of comfort and performance for our endurance line, we needed geometry uniquely aligned with the demands of long-distance riding and racing. In conjunction with the best geometry, we also needed to optimise frame topology and carbon layup.

Argon Fit System
Argon Fit System is designed to provide riders of all sizes with consistent performance and optimal positioning.

Pro Level Layup
We leave no room for compromise when we build bikes for the most demanding and passionate cyclists.
