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 Merida BIG.NINE 15 SE.
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.
