math/gearing help
So my bike has very short dropouts that allow for just about no adjustment, it is a conversion. Right now i run a 39/14 which is about a 1/3rd ratio it is a little rough for commuting and recreation all though managable but i was wondering if there was a way mathematically to determine my other gearing options using different cogs and chainrings. any help would be cool. thanks.

There are also eccentric hubs (the axle bolt is not in the center of the axle) to give you a little more range. As always, Sheldon Brown has the answers, or at least the links to the answers.
