Your inseam is just a bit long for someone 5'5". So the first bike shop may have picked a frame that is just a wee bit too large. I'd go back to the second shop and ask them to set up a bike for you to test ride that they think fits properly. Then compare your Cypress ride with it. While it is not true of all bike shops there are some that will sell without really doing a good fitting session for you. A good shop will take the time to make sure the bike is the correct fit. Riding should be fun, and if you are feeling like your going to fall over all of the time, it sure won't be. So, you are correct to be concerned with proper fit. I think there are many here who would say that proper fit is the most important thing, and others who would add that a good bike shop is worth it's weight in gold. Good luck with your efforts, and don't give up.
