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 MMR Adrenaline.

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 sizes are available for the MMR Adrenaline?

TrainCraft currently tracks these MMR Adrenaline sizes: XS, S, M, L, XL. The calculator uses each size's published geometry and stock cockpit assumptions to compare fit outcomes.
