That competitivecyclist.com fit calculator worked great for me, found it on this forum, put my measurements in and checked it against my mountain bikes/BMix setups and the figures matched it suggestions for cross country mountainbiking. Used it to size up a road bike, decided on the French Fit, used it to choose a bike to order and set it up, and got a used 55cm Bianchi and it fits fine, I'm 5'7".
The French Fit
"This fit features a taller front end (with a larger frame and/or head tube extension and stem), handlebar to saddle drops that are much closer to level, and favors riders who are looking to ease stress on the neck and back, ride as long and as far as they like, and are not concerned with the looking like an aggressive professional.
We recommend this fit for riders who really want to be comfortable and fast over longer distances. ....As an example, a person who might ride a 55cm or 56cm frame to achieve the Competitive Fit, might ride as much as a 59cm or 60cm in the French Fit.... An ideal compromise for those who can't shed their concern regarding stand over height is the choice of a "sized up" compact design to achieve a higher relative handlebar position. While bikes in the French Fit are not the racer's fashion they tend to look elegant, well proportioned, and ride like a dream."
