Echoing recomendations from above - PV Bikes is my new favorite bike store. I got my new Ruby from them, and while the bike fit was the main driver, the service was the reason I bought my bike there. They know bike fit, and will spend time with you to help find the right bike. Just like another bike store that I won't name used to be - I was really glad to find these guys.
It is a hike from the 562, however. It's one of those places that takes a hundred years to get to from any freeway. You would do well to call ahead and see what size bikes they have in stock. They had one or two closeouts when I was there a few weeks ago.
