Argon 18 SUM

The Argon Fit System is designed to provide riders of all sizes with consistent performance and optimal positioning. Regardless of your build, gender or your riding style, our frames are designed so that your fit will always be efficient and comfortable, ensuring the ultimate in handling. 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. While a lot of manufacturers optimise performance and weight targets for a medium size frame and simply scale up or down, we assess the performance of each size based on the individual character of that particular geometry. For example, even our largest frames have exceptional stiffness without excess weight, to avoid the 'dead' feel found in some XL frames. XS and XXS retain their inherent lightweight qualities, but without excess stiffness, avoiding harsh ride quality.

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.

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.

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. Through extensive research and analysis of stiffness, resistance, and aerodynamics using FEA and CFD software, we designed frames and forks that offer exceptional vertical compliance and dampens road-induced vibrations. At the same time, they needed to remain impervious to lateral movement, thus ensuring maximum pedaling efficiency for optimal power transfer. Our Topological Compliance System (TPS), was validated by numerous iterations of frame and fork designs tested both on the road and in our research and development laboratory using proprietary vibration testing tools.

We believe a good fit is the key to optimal performance. Argon 18’s proprietary 3D System is an integrated solution that extends the headtube for more flexible positioning options. Three headtube positions are possible for every frame size, increasing stiffness by 5% at 15mm and 11% at 25mm, versus traditional spacers. It allows also a larger fit windows (60mm of stack adjustment compared with 30 for a traditional setup). With this system, the handlebar height can be perfectly adjusted to meet the needs and preferences of every rider.
