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 Rakish.

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 Rakish?

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

Can I use the TrainCraft calculator for MMR Rakish sizing?

Yes. Open the calculator from this page to preload the MMR Rakish, then compare sizes against your body measurements, fit priorities, flexibility, and riding posture preferences.

What should I compare on the MMR Rakish before picking a size?

Start with stack, reach, effective top tube, and the stock stem/crank setup. TrainCraft uses those numbers to estimate cockpit reach, bar drop, saddle position, and how much adjustment headroom each size leaves.
