Description
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 Argon 18 to strip away all unnecessary weight within the new aero profile tube shapes – all while maintaining maximum power transfer.
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
Argon 18’s road race geometry is designed around the razor-sharp reflexes and precision handling required for racers of all levels.
Topological Compliance System
The Sum’s proprietary design method offers exceptional vertical compliance and dampened road-induced vibrations while retaining maximum stiffness. Each bike model featuring TCS technology was individually analysed to optimise frame topology and carbon layup.
Argon Fit System
Argon 18’s fit system offers size-specific geometries to provide optimal performance and positioning for all sizes, guaranteeing no rider left behind.
