I am only 5" 5.5' but my inseam is thisclose to 33 inches. It's interesting that our height difference is 4 inches yet our inseams are 1 inch. I'm planning to get a new bike and was told today that at 54 WSD would be my starting point. I don't know if there are any available (Trek 1.2) in WSD so I may go with a 52 cm in the mens version and adjust the front end of the bike accordingly.

HTH,
