Here is an illustration of the 52.5cm Stanforth Conway. This measurement refers to the effective seat tube length, the actual seat tube length is 43.1cm.

 

For a height of 5' 5" we have estimated an inside leg measurement of 749mm (29.5") and a saddle height of 662mm. Based on these estimates the standover height of the bike is circa 2cm lower than your inside leg measurement and with shoes you should have around 3cm of clearance.

 

It will be worthwhile measuring your inside leg measurement - if it's longer than 29.5" than it's likely the saddle will need to be higher than that shown in the image. To do this 1. Get a book and stand with your back against the wall, 2. Place the book in between your legs as high as it will go, 3. Move away from the wall keeping the book against the wall and finally, 4. measure from the top of the book to the floor. It will also be useful to measure the saddle height (bottom bracket centre to the top of the saddle) on your current bike and compare it against the illustrations.
