Nothing wrong with asking questions!

Be advised that bike sizes are kind of like clothing sizes: different manufacturers measure differently, and different styles fit differently. So a bike size is never an absolute.

FWIW, Fuji measures center to top (from the center of the BB shell to the top of the seat post), rather than center to center (center of BB shell to center of seat post-top tube joint) like many brands do. Makes it hard to compare sizes, especially when you factor in different frame angles, effective top tube, etc. IMO, reach is the more critical measurement. A bike that's too long or too short is never going to be comfy, and you can only do so much with changing stem length.

DH has a Fuji in the stable, and it's a 56, just like his Cannondale was and the Specialized is. In each case, the reach to the bars "drove" the size, not the amount of standover height (and no, he's not long-legged )

If it were me, I'd either try to ride the CL bike before buying or I'd go to my local Fuji dealer and try to ride a few models to get a sense of how they fit. Heck, I'd ride a few different brands, just for the experience and comparison.

Good luck! I know how the "want-bike" bug just knaws away at you! *is recovering from said syndrome after waiting 2 months for the new MTB*
