Argon 18 | SUM Road Carbon Frameset

Own the season.

The Argon 18 SUM is an elite-level road racing frameset built to attack the climbs, hold speed across the flats, and power through the final sprint.

Featuring the same performance-driven balance of aerodynamics and low weight as the SUM Pro, the SUM is an all-around race platform made for chasing KOMs and staying competitive across every part of the course. Rider-focused details such as dropped seat stays, refined sizing, the latest-generation 3D headset system, generous 30C tire clearance, and a non-proprietary cockpit make it fast, comfortable, and easier to personalize.

Key Features

• Elite-Level Engineering
A performance-driven balance of aerodynamic shaping and lightweight carbon construction creates a responsive race platform for every part of the course.

• Rider-Designed Compliance
Slender, dropped seat stays help absorb road vibration and keep the rider comfortable during long, demanding efforts.

• Latest-Generation 3D System
Argon 18’s adjustable headset system expands the available fit range without compromising front-end stiffness.

• Rider-Friendly Integration
A non-proprietary cockpit preserves the SUM’s clean appearance while allowing easier fitting, adjustment, and component selection.
