How to best determine if a bike will fit without riding it
The best answer to your question is simply "no."  Unless you've ridden the exact geometry before, there's no great way to know if your body will enjoy the fit.  Sure, there are MANY adjustments you can do to any bike to get it close, but nothing replaces taking the bike out for 20 miles to find out how your body will respond.

Now, with that said, if you haven't been riding a bike on a regular basis and only plan on riding this a limited amount of time, a good fitter could make a reasonable judgment call without any serious problems occurring later.  The bike can be tuned to your needs, as long as the general size is correct.
