Open MIN.D. Geometry & Size Chart
Open MIN.D. geometry (2026), compare stack, reach, and every supported size, then open the TrainCraft calculator with this bike preselected.
- Supported sizes
- S, M, L, XL
- Family
- This bike leans toward a taller front end and a more sustainable position for longer rides.
- What to compare
- Use this guide to compare stack, reach, and stock cockpit assumptions before choosing a frame size.

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 Open MIN.D..
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 Open MIN.D. should I get?
- It depends on more than your height. Two riders of the same height can need different Open MIN.D. 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 Open MIN.D. 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 Open MIN.D..
- Should I size up or down on the Open MIN.D.?
- 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 Open MIN.D.?
- TrainCraft currently tracks these Open MIN.D. sizes: S, M, L, XL. The calculator uses each size's published geometry and stock cockpit assumptions to compare fit outcomes.
