First .... test-ride a 58 if you can.

Then, if you can't ... go by the numbers listed. If reach increases a very small amount, you can easily readjust with a slightly shorter stem, which will have minimal impact on operations or aesthetics. You can also buy a stem which angles up sharply, giving you an even more upright rising position. It might look odd to some "purists," but they won't be paying for or riding it.

I guess I would look at it this way, if none of that worked .... How much do you plan to spend on the bike, and how long do you hope to keep it? For me, if I had to spend a weekend day and a few gallons of gas driving to a particular store to test-ride a particular bike in order to make sure that a multi-year, multi-thousand dollar investment wasn't wasted ....
