\definefontfamily [mainface] [sans] [Ubuntu]

\definefallbackfamily [mainface] [math] [Ubuntu] [preset=math:lowercaseitalic]
\definefallbackfamily [mainface] [math] [Ubuntu] [preset=math:lowercasenormal]

\definefontfamily     [mainface] [math] [Latin Modern Math]

\setupbodyfont[mainface]

\starttext
$ abc \max$ abc max
\stoptext

BTW: Why do you set the upright, italic etc. styles by hand?

The presets are defined in font-eel.mkvi with the \definefontfamilypreset command.
