So you'd rather spend several thousand dollars on a bike (or two) and take the advice of internet folks who have never seen you and know next to nothing about you, your riding style, etc.? If you are willing to spend that kind of dough on bikes, the cost of a fit session seems minimal. Consider the cost of a proper fit as an investment, not an expense. Riding a properly fitted bike is a wonderful experience.

I'd have to believe Trek shops - whose bikes you seem to be focused on - offer fit sessions. Some fitters will give you a discount on a bike if you purchase it from them (don't know Trek shops offer this, you could always ask).

Good luck.
