Argon 18 Grey Matter

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.

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.
