I've already got two bikes (three, if you count my cheap, one-speed neighborhood cruiser), but I'm thinking of going for a professional fitting. I got a Waterford touring bike several years ago, and I got a deal on it because it was actually built for someone else; but I was able to tweak it with components to get it pretty comfortable. Then I got a Bianchi Veloce last fall, in the deal of the century, because the Waterford is pretty heavy and I wanted a light, fast bike for club rides--also needed tweaking for comfort, but it's still not quite right.

So, after all that, I'm thinking that maybe what I need is someone to help me figure out the bike size that's really right for me. Which means a professional fitting. Here's my concern: will a professional fitter want to fit me for an aggressive riding position? Because that's not what I want. I want to be comfortable enough to stay in that saddle for hours (well, with a break now and then of course ). Also, I'm in my 50s and not at the *ahem* optimum weight for my height, and I'm afraid that a professional fitter will just look at me and think "Oh brother, why am I wasting my time with this podgy old woman?"

Finally, what will I end up with when the fitting is done? Does the fitter give you a specific geometry to look for, or suggest actual frames/bikes?

There's a shop about a 2-hour drive from here that offers Serotta fittings, so that's the specific one I have in mind. But I thought I'd get some thoughts from the TE forum brain trust before taking the plunge. Thanks for any tips you all have to offer.
