You could go to 5 different 'bike fitters' and end up with 5 distinctly different set-ups. You need to find someone that understands then type of riding you plan on doing and is comfortable doing fittings for that. Some fitters are very caught up in 'racing' fits and will set up most of their clients in a similar way. I worked with a guy for years that thought every custom frame he did a fitting for needed a head tube extension. I'm surprised that the frame builders would actually make some of these frames. Ask around when you're riding w/ groups, see what others have to say about this. And of course ignore lowrider's advice. If you knew what you wanted you'd just buy it or have it made.
