Most rye bread you get would be a mix of rye flour with wheat flour, and it's mostly wheat flour.

The rye breads I make regularly contain 2/3 rye flour and 1/3 wheat flour. This is a "mixed" bread, a real rye bread would contain even less wheat flour.

A pure rye bread would be more difficult to bake as it binds water differently but I think its doable. It might not be as tasty but you wouldn't starve in front of it.

Which is why I said "good bread" Sure you can make lots of other ones but without wheat it isn't as tasty.
