You have all heard of the stem fitting guide ( if the front wheel axel is behind the handlebars, the stem is too long, vice versa).
Does the stem angle affect the the handlebar/axle correlation?
For example, assuming both stems are the same length and correct length, will a 6* stem and 25* stem both have the handlebars over the front wheel axle?
You're asking the wrong question.
The answer to the right question is that the axle/bar relationship isn't a useful fit guide.
