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. 

All Together Faster

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. CFD analysis shows the Sum Pro's aero performance as equivalent to the all-aero Nitrogen and 9% faster than the Gallium Pro Disc. A lightweight layup is complemented by a minimalist candy clearcoat directly over the carbon. Design details like dropped seatstays and an indented seattube assure compliance in all the right places to keep you rooted in the saddle. An updated size range reflects our knowledge of rider fit, providing the best handling and positioning across all sizes.

Light, fast and designed to keep you on the road all day, the all-new Sum Pro is your bike for the classics, the crits, the climbs… and any challenge you find in between.


Argon Fit System

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

Road Race Geometry

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

Pro Level Layup

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

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 optimize frame topology and carbon layup.


Argon 18’s proprietary 3D System is an integrated solution that extends the headtube for more positioning options.
