All Together Faster
Decisions, decisions… made easy. With a bike that gives you flat-out advantage on the climbs, the sprints and the straightaways, the only decision you’ll need to make is how nice you want to be to the other guys. A rider-oriented design approach ensures a frame that is both rooted and responsive, with a ride experience most aero frames can’t match. With a layup engineered to maximise aerodynamics while keeping weight low, the design process for the Sum allowed us to strip away all unnecessary weight within the new aero profile tube shapes - all while maintaining maximum power transfer.
Ideal for
From the classics to the centuries, the Sum is engineered to keep you in churning out the watts no matter what the course - or the competition - throws at you.
Core Technologies
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.
Elite Level Layup
We believe the discerning cyclist deserves more than just trickle-down technology. Our Elite level bikes benefit from the same attention to detail as our Pro level ones.
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.
3D
Argon 18’s proprietary 3D System is an integrated solution that extends the headtube for more positioning options.
