The Nitrogen delivers speed, lightness, fit and ride optimization.
Out-of-this-world Performance - at Real-World Prices
We believe the discerning cyclist deserves more than just trickle-down technology. We make sure our Elite level bikes benefit from the same attention to detail and offer the same riding characteristics as our Pro level ones. From their carbon layup right down to the smallest parts, all aspects of their design are optimized so that they are guaranteed to be overachievers in their own right.
Precision positioning
Our performance road geometry prioritises the needs of racers: holding a low, aero position, having confident handling on technical courses and in bunch sprints, and highly efficient power transfer. These bikes often feature aero tube shapes or tube shapes designed for maximum stiffness at key areas, like the bottom bracket. A lower front end and longer top tube than our endurance geometry let you achieve that aero position, and a narrower wheelbase provides the razor-sharp reflexes for those tight corners and quick handling in the bunch. Argon 18 bikes have a lower bottom bracket than most, which makes these bike exceptionally stable, and enhances their renowned ride quality.
Size-specific geometries to provide optimal performance and positioning for all riders
Argon 18's fit system offers size-specific geometries to provide optimal performance and positioning for all sizes, guaranteeing no rider left behind.
Our smallest bike frames offer the same ride feel as our largest frames. In fact, our XL frames have exceptional stiffness without excess weight, to avoid the 'dead' feel found in some larger frames. XS and XXS retain their inherent lightweight qualities, but without excess stiffness, avoiding harsh ride quality.
More than one fork to match frame sizing
For every model, 2 fork sizes are developed (1 fork for smaller sizes and 1 fork for larger sizes) to assure balanced handling and avoid toe overlap. Steerer angle, fork length, and fork rake are optimized to assure the best fork trail angle and handling for every size.
Wide fit window & stack and reach
We offer sizing from XXS to XL in all of our road bikes, and XS to XL in our Tri bikes with each size approached individually from a design and performance perspective.
