hi - i'm rather stunned to hear of the fitting practicies (or lack thereof) of these LBS! I think of all the dimensions, going solely and only off of top tube height is not wise. How often are you going to straddle your bike, perfectly centered, and flat-footed???

I think other dimensions are much more important - proper leg extension (seat tube height - crank length), back/shoulder (top tube length - handlebar height/width.

I wouldn't buy a bike from a shop, unless they did a fitting - usually for a test ride - since testing a bike that isn't set-up for you, is not generally going to work.

I'd strongly consider going outside of those LBS, and finding one that treats you right.

About the bikes....I have an '07 Trek 1600 WSD - I absolutely love it. I'm a big fan of the WSD designs. Trek is a quality brand, others are too, but that's just my experience. My advice is to try as many bikes as possible (with a proper fit!) and then see what works. If it fits you, a Trek Pilot would be a terrific ride.

Best of luck and please let us know about your new bike
