Russell Cree at Upper Echelon did my bike fit a few years ago. He knows his stuff. Basically, unless you are complaining about back issues (or something is really out of whack), he doesn't really do much with the upper body; he is more about the leg motion. He is not a trackie, but he is up to date on racing cyclist biomechanics. He's got a fancy motion tracking machine. I recommend him primarily because when I went in, I had already been racing a few years; thought my position was pretty good (until I started getting some niggling injuries). He looked at me with that motion tracking machine, raised my saddle like a full inch, and all my troubles literally went away. Goes to show the limits of a self-fit.
At Bike Central, Dean will fit you by eye, watching you as you ride. He's not a fit specialist per se, but he does know what a good fit looks like and a lot of guys swear by him. Just ask. He might bite your head off, but only if you deserve it
.
Those are the only two I know about personally. Russell will put you back a C note or two. Good fits are not cheap. Don't know what Dean charges.
