The Sum Pro in action
Technology Sum Pro
For our newest generation of bikes, we wanted to push our 3D System even further by merging it seamlessly with the frame.
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.
Pro Level Layup
We leave no room for compromise when we build bikes for the most demanding and passionate cyclists.
