This chart organizes the most common bodies from Standard Clay, Montesa, and SIO-2 into compatibility groups, so you can quickly see which ones can share a build. Use the tabs to switch between brands.
Read my latest blog post to see everything I’ve been testing.
A few things to keep in mind: Standard Clay and SIO-2 publish shrinkage data, so their groups are based on exact percentages. Montesa doesn't publish shrinkage, so their groups are organized by firing temperature instead, same logic, different data.
This is a living document. If you work with a brand that's not listed here, leave a comment or send me a message and I'll add it.
