SUM - Ultegra Di2 Road Bike - Podium Grey (2024)
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.
Own the season: the Sum will get you ahead on the climbs, keep you there on the flats, and power you through the sprints.
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
Our road race geometry is designed around the razor-sharp reflexes and precision handling required for racers of all levels.
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.
Argon Fit System
Argon Fit System is designed to provide riders of all sizes with consistent performance and optimal positioning.
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.
