How to use this guide
Start with the size table to narrow the geometry range you actually want. Then open the calculator to compare that geometry against your body dimensions, flexibility, and fit priorities.
The TrainCraft bike fit tool models saddle height, cockpit reach, and bar drop using the frame geometry plus stock cockpit assumptions for the Focus Atlas 8 (Carbon).
That is more useful than a generic height chart because two sizes can both fit your height while requiring very different stems, spacers, or saddle positions.

FAQ
- What size Focus Atlas 8 (Carbon) should I get?
- It depends on more than your height. Two riders of the same height can need different Focus Atlas 8 (Carbon) sizes, because inseam, torso length and flexibility change the reach and bar drop that suit them. Enter your height and inseam in the size check on this page to see which size fits you.
- What height is each Focus Atlas 8 (Carbon) size for?
- Height ranges are only a rough guide: they overlap, and riders near the edge of a range often fit the next size better. The size check on this page uses your height and inseam to show where you land on the Focus Atlas 8 (Carbon).
- Should I size up or down on the Focus Atlas 8 (Carbon)?
- Between two sizes, the smaller frame usually needs a longer stem and more spacers, and the larger one a shorter stem and a lower front. Which one works depends on your body and flexibility. The size check shows your size; the full fit gives the exact setup that size needs.
- What sizes are available for the Focus Atlas 8 (Carbon)?
- TrainCraft currently tracks these Focus Atlas 8 (Carbon) sizes: XS, S, M, L, XL. The calculator uses each size's published geometry and stock cockpit assumptions to compare fit outcomes.
