It's ok Geyser - doubt his expertise. Someone who "looks at you", has you sit on a bike for a brief period of time and then tells you the frame size you need, is just guessing. Any good LBS will give you a bike fit and they should do it without charging you if you're having it done in order to buy a bike. Especially a higher end bike. I would either find another bike shop or find someone else at that LBS that inspires more confidence in you.

After all, you won't ride a bike that doesn't fit AND....it's YOUR money!
