How Argon 18 sizing works
TrainCraft covers 4 Argon 18 models, and all of them use lettered sizes (S, M, L and so on). A letter is a label, not a measurement: the same letter sits on different stack and reach from one model to the next.
Stack and reach decide how a frame fits. Each model below lists them for every size, and the calculator reads your result against that geometry.

Frequently asked questions
- What size Argon 18 should I get?
- It depends on the model as much as on you. Argon 18 frame sizes are set per model, and two riders of the same height can need different sizes depending on inseam and torso length. Pick your model in the calculator at the top of this page, enter your height and inseam, and the check shows which size fits you.
- How do I find my Argon 18 frame size?
- Choose the Argon 18 model you are looking at, then enter your height and inseam in the size check. It compares your measurements with that model's stack and reach for every size. The model pages below show the full geometry.
- Is a Argon 18 size the same on every model?
- No. Size labels are set per model, and the same label can have different stack and reach on another model. Check the model you plan to buy, not the label alone.
