The Argon 18 Sum Pro is a high-speed bike designed for all types of road riding.
It takes the all-around capabilities and technical lightweight handling of the Gallium and merges it with the aerodynamic efficiency of the Nitrogen. This versatile bike is built to conquer climbs, crits, and classics with ease, offering race-ready handling and premium ride quality for a fast yet comfortable experience over long distances. Whether you need to sprint on a flat road or climb uphill, the Sum Pro has got you covered.
Aerodynamics play a crucial role in the Sum Pro's success. The frame's design is 9 percent faster than the Gallium Disc, thanks to CFD analysis, and is equivalent to the aero speed of the Nitrogen. The dropped seatstays and indented seat tube keep you in the ideal aero position while ensuring comfort. An updated size range caters to riders of all sizes, with a focus on perfect rider position across the board. The 3D+ integrated front end and Argon 18's Road Race Geometry enhance the handling, especially at high speeds, for the fastest and most technically accurate performance on every ride.
The Sum Pro's frame boasts the Pro Level Layup, Argon 18's premier carbon fiber build, ensuring top-notch professional-level performance. This technology allows for a lightweight frame that remains as fast as a typical aero road bike. The Topological Compliance System adds endurance-like compliance to the bike, making it perfect for long-distance riders. With its exceptional features and performance, the Argon 18 Sum Pro is an excellent companion for any road ride.
