Let's not confuse the issue by saying that drop bars equals racing bikes.
Most people find that for long days in the saddle touring a racing bike with its shorter wheelbase, and narrower, harder tires is not as comfortable as a touring bike. A touring bike affords riders the option of not bending over as much which is easier on our backs. Try to get the bars even with the saddle on a newer racing bike. I've never seen someone buy a touring bike complain about comfort, but lots of people who buy racing frames who are uncomfortable, especially the older rider (I'm 55 and that means me). Fit, fit, fit, touring frame or not is the key. FitKit is fine but a real pro can do it just as well by watching you ride on a trainer and asking you what kind of riding you do.
