Hi all! Newbie here. Well, I am new to the forums and new to the world of road bikes, but I do own a little Kona mtn bike that I love dearly. On with my issue..

I just put down money on an 05 Dolce Comp tonight. I was looking at it and the Pilot 2.1 (womens), but figured I would go for the long haul. Here's my "issue" though...

I visited three stores. The first store told me I would need a 48 frame. The second store, which put me on a womens PIlot 2.1, took my measurements, plugged them into a computer, and told me that I needed a 50 frame. Tonight, at LBS number 3, I got the 48 frame, which the guy said was my size and which felt fine. The 50 frame felt fine as well. I'm confused? The geometry of the 2.1 and Dolce are almost identical... Should I be concerned? The only thing that needed to be done on the Dolce was the guy lowered the seat and moved it back a hair. It *felt* fine and I do trust the store, but I'm still... perplexed. Are those computer things reliable? I'm a smidden over 5 feet tall and my inseam is about a 26.5/27.
