Hello, Please try the following:
\starttext
\input tufte
\startnarrower
\midaligned{some text which should be centered but is not}
\input tufte
\rightaligned{some text which should be right-aligned but is not}
\stopnarrower
\input tufte
\stoptext
Please note that the ...aligned text is shifted too much to the
right in both cases. Prefixing a \noindent is of no use.
