Kk, I looked at the link to your LBS! No mention of measuring so it could be a classic high street type shop (the cycling equivalent of JJB Sports) . You need to find a shop that will measure you properly as in floor to crutch, shoulder width, arm length, etc. The kids method of checking you can reach the ground isn't how to do it. The wrong frame size will lead to injury. I guess you are bored of everyone saying that now! If you look on the bike shop link I posted they have a picture of a measuring jig! That's what you need to see in whatever bike shop you use.
